DO NOT USE. THE FUNCTIONALITY IS SUBJECT TO CHANGE WITHOUT PRIOR NOTICE. TCP multiplexer daemon listens on all network interfaces on TCP port specified by argument PORT. On each incoming connection it performs TCPMUX handshake as defined in RFC 1078. Then it hands the connection to the application bound to the service name specified by the client (see linknanomsg:tcpmux[7] for more details). OPTIONS ------- There are no options defined.

On most systems, 'errno' can be accessed directly and this function is not needed. However, on Windows, there are multiple implementations of the CRT library (single-threaded, multi-threaded, release, debug) and each of them has its own instance of 'errno'. Thus, if nanomsg library and the application that uses it link with different versions of CRT library, they don't share same instance of 'errno'. Consequently, error codes set by nanomsg cannot be accessed by the application. To overcome this problem, application can use _nn_errno()_ function to retrieve the nanomsg's value of 'errno'. RETURN VALUE ------------ Returns value of 'errno' for the current thread. ERRORS ------ No errors are defined. EXAMPLE ------- ---- rc = nn_send (s, "ABC", 3, 0); if (rc < 0) printf ("nn_send failed with error code %d\n", nn_errno ()); ---- SEE ALSO -------- linknanomsg:nn_strerror[3] linknanomsg:nanomsg[7] AUTHORS ------- Martin Sustrik nanomsg-0.8-beta/doc/nn_strerror.txt0000664000175000017500000000137612623652600020534 0ustar00travistravis00000000000000nn_strerror(3) ============== NAME ---- nn_strerror - convert an error number into human-readable string SYNOPSIS -------- *#include * *const char *nn_strerror (int 'errnum');* DESCRIPTION ----------- Converts error number (errno) into a human-readable string. As opposed to 'strerror(3)' this function handles nanomsg-specific errors in addition to standard system errors. RETURN VALUE ------------ Return error message string. ERRORS ------ No errors are defined. EXAMPLE ------- ---- rc = nn_send (s, "ABC", 3, 0); if (rc < 0) printf ("nn_send failed: %s\n", nn_strerror (errno)); ---- SEE ALSO -------- linknanomsg:nn_errno[3] linknanomsg:nn_symbol[3] linknanomsg:nanomsg[7] AUTHORS ------- Martin Sustrik nanomsg-0.8-beta/doc/nn_symbol.txt0000664000175000017500000000353712623652600020160 0ustar00travistravis00000000000000nn_symbol(3) ============ NAME ---- nn_symbol - query the names and values of nanomsg symbols SYNOPSIS -------- *#include * *const char *nn_symbol (int 'i', int '*value');* DESCRIPTION ----------- Retrieves the symbol name and value at index 'i'. Indices start at 0. An index has no significance to its associated symbol; the mappings may change between library versions. Typically a client will iterate through the symbols until nn_symbol returns NULL in order to collect all the symbols. All symbols exposed by 'nn_symbol' are available directly in the C API, generally as preprocessor macros. Thus, this function is useful mostly for language bindings that can't parse the header file and rely on retrieving the symbols in the runtime. Note that the NN_MSG symbol is not exported by the _nn_symbol_ function. First, it is a pointer rather than an integer; second, the symbol is not supposed to be exported from language bindings to the user. Instead, language bindings should provide the zero-copy functionality in a language-specific way, if at all (zero-copy functionality may not make sense for some languages/bindings). RETURN VALUE ------------ If 'i' is valid, returns the name of the symbol at that index. If the pointer 'value' is not NULL, the symbol's value is stored there. If 'i' is out-of-range, nn_symbol returns NULL and sets 'errno' to EINVAL. ERRORS ------ *EINVAL*:: The passed index 'i' was out-of-range; it was less than zero or greater-than-or- equal-to the number of symbols. EXAMPLE ------- ---- int value, i; for (i = 0; ; ++i) { const char* name = nn_symbol (i, &value); if (name == NULL) break; printf ("'%s' = %d\n", name, value); } ---- SEE ALSO -------- linknanomsg:nn_symbol_info[3] linknanomsg:nn_errno[3] linknanomsg:nn_strerror[3] linknanomsg:nanomsg[7] AUTHORS ------- Evan Wies nanomsg-0.8-beta/doc/nn_symbol_info.txt0000664000175000017500000001035412623652600021166 0ustar00travistravis00000000000000nn_symbol_info(3) ================= NAME ---- nn_symbol_info - query the names and properties of nanomsg symbols SYNOPSIS -------- *#include * *int nn_symbol_info (int 'i', struct nn_symbol_properties '*buf', int 'buflen');* DESCRIPTION ----------- Retrieves the symbol name and value at index 'i'. Indices start at 0. An index has no significance to its associated symbol; the mappings may change between library versions. The nn_symbol_properties has the following definition: ---- struct nn_symbol_properties { /* The constant value */ int value; /* The constant name */ const char* name; /* The constant namespace, or zero for namespaces themselves */ int ns; /* The option type for socket option constants */ int type; /* The unit for the option value for socket option constants */ int unit; }; ---- More structure members may be added in future, but input pointer will be written only up to 'buflen' so ABI is forward-compatible. Typically a client will iterate through the symbols until nn_symbol_info returns NULL in order to collect all the symbols. All symbols exposed by 'nn_symbol_info' are available directly in the C API, generally as preprocessor macros. Thus, this function is useful mostly for language bindings that can't parse the header file and rely on retrieving the symbols in the runtime. Note that the NN_MSG symbol is not exported by the 'nn_symbol_info' function. First, it is a pointer rather than an integer; second, the symbol is not supposed to be exported from language bindings to the user. Instead, language bindings should provide the zero-copy functionality in a language-specific way, if at all (zero-copy functionality may not make sense for some languages/bindings). AVAILABLE NAMESPACES -------------------- *NN_NS_NAMESPACE*:: Equals to zero and denotes the NN_NS_* constants themselves *NN_NS_VERSION*:: Nanomsg version constants *NN_NS_DOMAIN*:: Socket domain (or address family) constants AF_SP, AF_SP_RAW *NN_NS_TRANSPORT*:: Transport name constants (used for socket options mainly) *NN_NS_PROTOCOL*:: Socket protocol constants *NN_NS_OPTION_LEVEL*:: Socket option level constants (NN_SOL_SOCKET) *NN_NS_SOCKET_OPTION*:: Socket options for NN_SOL_SOCKET level *NN_NS_TRANSPORT_OPTION*:: Socket options for transport level (used with transport constants) *NN_NS_OPTION_TYPE*:: The option types (described below) *NN_NS_FLAG*:: The nn_send/nn_recv flags (only NN_DONTWAIT for now) *NN_NS_ERROR*:: The errno values *NN_NS_LIMIT*:: Various nanomsg limits (only NN_SOCKADDR_MAX for now) *NN_NS_EVENT*:: Event flags (bit mask) for use with nn_poll (NN_POLLIN, NN_POLLOUT) AVAILABLE OPTION TYPES ---------------------- *NN_TYPE_NONE*:: No type, is returned for constants that are not socket options *NN_TYPE_INT*:: The integer type *NN_TYPE_STR*:: String (char *) type More types may be added in future nanomsg. You may enumerate all of them using the 'nn_symbol_info' itself by checking 'NN_NS_OPTION_TYPE' namespace. AVAILABLE OPTION UNITS ---------------------- *NN_UNIT_NONE*:: No unit, is returned for constants that are not socket options, or do not have any meaningful unit (strings, integer values) *NN_UNIT_BYTES*:: The option value is expressed in bytes *NN_UNIT_MILLISECONDS*:: The option value is expressed in milliseconds *NN_UNIT_PRIORITY*:: The option value is a priority, an integer from 1 to 16 *NN_UNIT_BOOLEAN*:: The option value is boolean, an integer 0 or 1 More types may be added in future nanomsg. You may enumerate all of them using the 'nn_symbol_info' itself by checking 'NN_NS_OPTION_TYPE' namespace. RETURN VALUE ------------ If 'i' is valid, returns the number of bytes stored at the structure. The maximum value that can be returned is 'buflen'. If 'i' is out-of-range, nn_symbol_info returns zero.

If a socket is blocked inside a blocking function, such as linknanomsg:nn_recv[3], it will be unblocked and ETERM error will be returned to the user. Similarly, any subsequent attempt to invoke a socket function other than linknanomsg:nn_close[3] after _nn_term()_ was called will result in ETERM error. If waiting for _NN_SNDFD_ or _NN_RCVFD_ using a polling function, such as _poll()_ or _select()_, the call will unblock with both _NN_SNDFD_ and _NN_RCVFD_ signaled. The _nn_term()_ function itself is non-blocking.

The content of the message is undefined after allocation and it should be filled in by the user. While linknanomsg:nn_send[3] and linknanomsg:nn_sendmsg[3] allow to send arbitrary buffers, buffers allocated using _nn_allocmsg()_ can be more efficient for large messages as they allow for using zero-copy techniques. 'type' parameter specifies type of allocation mechanism to use. Zero is the default one, however, individual transport mechanisms may define their own allocation mechanisms, such as allocating in shared memory or allocating a memory block pinned down to a physical memory address. Such allocation, when used with the transport that defines them, should be more efficient than the default allocation mechanism. RETURN VALUE ------------ If the function succeeds pointer to newly allocated buffer is returned. Otherwise, NULL is returned and 'errno' is set to to one of the values defined below. ERRORS ------ *EINVAL*:: Supplied allocation 'type' is invalid. *ENOMEM*:: Not enough memory to allocate the message.

Note that as with the standard _realloc_, the operation may involve copying the data in the buffer. RETURN VALUE ------------ If the function succeeds pointer to newly allocated buffer is returned. Otherwise, NULL is returned and 'errno' is set to to one of the values defined below. ERRORS ------ *ENOMEM*:: Not enough memory to allocate the message.

While linknanomsg:nn_recv[3] and linknanomsg:nn_recvmsg[3] allow to receive data into arbitrary buffers, using library-allocated buffers can be more efficient for large messages as it allows for using zero-copy techniques. RETURN VALUE ------------ If the function succeeds zero is returned. Otherwise, -1 is returned and 'errno' is set to to one of the values defined below.

Returns a file descriptor for the newly created socket. Following domains are defined at the moment: *AF_SP*:: Standard full-blown SP socket. *AF_SP_RAW*:: Raw SP socket. Raw sockets omit the end-to-end functionality found in AF_SP sockets and thus can be used to implement intermediary devices in SP topologies. 'protocol' parameter defines the type of the socket, which in turn determines the exact semantics of the socket. Check manual pages for individual SP protocols to get the list of available socket types. The newly created socket is initially not associated with any endpoints. In order to establish a message flow at least one endpoint has to be added to the socket using linknanomsg:nn_bind[3] or linknanomsg:nn_connect[3] function. Also note that 'type' argument as found in standard _socket(2)_ function is omitted from _nn_socket_. All the SP sockets are message-based and thus of _SOCK_SEQPACKET_ type. RETURN VALUE ------------ If the function succeeds file descriptor of the new socket is returned. Otherwise, -1 is returned and 'errno' is set to to one of the values defined below. Note that file descriptors returned by _nn_socket_ function are not standard file descriptors and will exhibit undefined behaviour when used with system functions. Moreover, it may happen that a system file descriptor and file descriptor of an SP socket will incidentally collide (be equal). ERRORS ------ *EAFNOSUPPORT*:: Specified address family is not supported. *EINVAL*:: Unknown protocol. *EMFILE*:: The limit on the total number of open SP sockets or OS limit for file descriptors has been reached. *ETERM*:: The library is terminating.

Any buffered inbound messages that were not yet received by the application will be discarded. The library will try to deliver any outstanding outbound messages for the time specified by _NN_LINGER_ socket option. The call will block in the meantime. RETURN VALUE ------------ If the function succeeds zero is returned. Otherwise, -1 is returned and 'errno' is set to to one of the values defined below. ERRORS ------ *EBADF*:: The provided socket is invalid. *EINTR*:: Operation was interrupted by a signal. The socket is not fully closed yet. Operation can be re-started by calling _nn_close()_ again.

The 'level' argument specifies the protocol level at which the option resides. For generic socket-level options use _NN_SOL_SOCKET_ level. For socket-type-specific options use socket type for 'level' argument (e.g. _NN_SUB_). For transport-specific options use ID of the transport as the 'level' argument (e.g. _NN_TCP_). The value is stored in the buffer pointed to by 'optval' argument. Size of the buffer is specified by the 'optvallen' argument. If the size of the option is greater than size of the buffer, the value will be silently truncated. Otherwise, the 'optvallen' will be modified to indicate the actual length of the option. __ header defines generic socket-level options (_NN_SOL_SOCKET_ level). The options are as follows: *NN_DOMAIN*:: Returns the domain constant as it was passed to _nn_socket()_. *NN_PROTOCOL*:: Returns the protocol constant as it was passed to _nn_socket()_. *NN_LINGER*:: Specifies how long the socket should try to send pending outbound messages after _nn_close()_ have been called, in milliseconds. Negative value means infinite linger. The type of the option is int. Default value is 1000 (1 second). *NN_SNDBUF*:: Size of the send buffer, in bytes. To prevent blocking for messages larger than the buffer, exactly one message may be buffered in addition to the data in the send buffer. The type of this option is int. Default value is 128kB. *NN_RCVBUF*:: Size of the receive buffer, in bytes. To prevent blocking for messages larger than the buffer, exactly one message may be buffered in addition to the data in the receive buffer. The type of this option is int. Default value is 128kB. *NN_RCVMAXSIZE*:: Maximum message size that can be received, in bytes. Negative value means that the received size is limited only by available addressable memory. The type of this option is int. Default is 1024kB. *NN_SNDTIMEO*:: The timeout for send operation on the socket, in milliseconds. If message cannot be sent within the specified timeout, EAGAIN error is returned. Negative value means infinite timeout. The type of the option is int. Default value is -1. *NN_RCVTIMEO*:: The timeout for recv operation on the socket, in milliseconds. If message cannot be received within the specified timeout, EAGAIN error is returned. Negative value means infinite timeout. The type of the option is int. Default value is -1. *NN_RECONNECT_IVL*:: For connection-based transports such as TCP, this option specifies how long to wait, in milliseconds, when connection is broken before trying to re-establish it. Note that actual reconnect interval may be randomised to some extent to prevent severe reconnection storms. The type of the option is int. Default value is 100 (0.1 second). *NN_RECONNECT_IVL_MAX*:: This option is to be used only in addition to _NN_RECONNECT_IVL_ option. It specifies maximum reconnection interval. On each reconnect attempt, the previous interval is doubled until _NN_RECONNECT_IVL_MAX_ is reached. Value of zero means that no exponential backoff is performed and reconnect interval is based only on _NN_RECONNECT_IVL_. If _NN_RECONNECT_IVL_MAX_ is less than _NN_RECONNECT_IVL_, it is ignored. The type of the option is int. Default value is 0. *NN_SNDPRIO*:: Retrieves outbound priority currently set on the socket. This option has no effect on socket types that send messages to all the peers. However, if the socket type sends each message to a single peer (or a limited set of peers), peers with high priority take precedence over peers with low priority. The type of the option is int. Highest priority is 1, lowest priority is 16. Default value is 8. *NN_RCVPRIO*:: Sets inbound priority for endpoints subsequently added to the socket. This option has no effect on socket types that are not able to receive messages. When receiving a message, messages from peer with higher priority are received before messages from peer with lower priority. The type of the option is int. Highest priority is 1, lowest priority is 16. Default value is 8. *NN_IPV4ONLY*:: If set to 1, only IPv4 addresses are used. If set to 0, both IPv4 and IPv6 addresses are used. The type of the option is int. Default value is 1. *NN_SNDFD*:: Retrieves a file descriptor that is readable when a message can be sent to the socket. The descriptor should be used only for polling and never read from or written to. The type of the option is same as the type of file descriptor on the platform. That is, int on POSIX-complaint platforms and SOCKET on Windows. The descriptor becomes invalid and should not be used any more once the socket is closed. This socket option is not available for unidirectional recv-only socket types. *NN_RCVFD*:: Retrieves a file descriptor that is readable when a message can be received from the socket. The descriptor should be used only for polling and never read from or written to. The type of the option is same as the type of file descriptor on the platform.

This socket option is not available for unidirectional send-only socket types. *NN_SOCKET_NAME*:: Socket name for error reporting and statistics. The type of the option is string. Default value is "N" where N is socket integer. *This option is experimental, see linknanomsg:nn_env[7] for details* RETURN VALUE ------------ If the function succeeds zero is returned. Otherwise, -1 is returned and 'errno' is set to to one of the values defined below.

The new value is pointed to by 'optval' argument. Size of the option is specified by the 'optvallen' argument. __ header defines generic socket-level options (_NN_SOL_SOCKET_ level). The options are as follows: *NN_LINGER*:: Specifies how long the socket should try to send pending outbound messages after _nn_close()_ have been called, in milliseconds. Negative value means infinite linger. The type of the option is int. Default value is 1000 (1 second). *NN_SNDBUF*:: Size of the send buffer, in bytes.

The message will be 'len' bytes long. Alternatively, to send a buffer allocated by linknanomsg:nn_allocmsg[3] function set the buf parameter to point to the pointer to the buffer and 'len' parameter to _NN_MSG_ constant. In this case a successful call to _nn_send_ will deallocate the buffer. Trying to deallocate it afterwards will result in undefined behaviour.

If the message cannot be sent straight away, the function will fail with 'errno' set to EAGAIN. RETURN VALUE ------------ If the function succeeds, the number of bytes in the message is returned. Otherwise, -1 is returned and 'errno' is set to to one of the values defined below. ERRORS ------ *EFAULT*:: 'buf' is NULL or 'len' is NN_MSG and the message pointer (pointed to by 'buf') is NULL. *EBADF*:: The provided socket is invalid. *ENOTSUP*:: The operation is not supported by this socket type. *EFSM*:: The operation cannot be performed on this socket at the moment because the socket is not in the appropriate state. This error may occur with socket types that switch between several states. *EAGAIN*:: Non-blocking mode was requested and the message cannot be sent at the moment. *EINTR*:: The operation was interrupted by delivery of a signal before the message was sent. *ETIMEDOUT*:: Individual socket types may define their own specific timeouts.

Any bytes exceeding the length specified by the 'len' argument will be truncated. Alternatively, _nanomsg_ can allocate the buffer for you. To do so, let the 'buf' parameter be a pointer to a void* variable (pointer to pointer) to the receive buffer and set the 'len' parameter to _NN_MSG_. If the call is successful the user is responsible for deallocating the message using the linknanomsg:nn_freemsg[3] function.

If such timeout is hit this error will be returned. *ETERM*:: The library is terminating. EXAMPLES -------- Receiving a message into a buffer allocated by the user:: This example code will retrieve a message of either 100 bytes or less. If a larger message was sent it will be truncated to 100 bytes. ---- char buf [100]; nbytes = nn_recv (s, buf, sizeof (buf), 0); ---- Receiving a message into a buffer allocated by _nanomsg_:: The following will get a message from the pipe with a buffer allocated by the system. It is large enough to accommodate the entire message. This is a good way to get the entire message without truncating if the size of the message is unknown. It is the user's responsibility to call linknanomsg:nn_freemsg[3] after processing the message. ---- void *buf = NULL; nbytes = nn_recv (s, &buf, NN_MSG, 0); if (nbytes < 0) { /* handle error */ ... } else { /* process message */ ... nn_freemsg (buf); } ---- Note that this can be more efficient than manually allocating a buffer since it is a zero-copy operation.

If only one socket is valid and the other is negative, _nn_device_ works in a "loopback" mode -- it loops and sends any messages received from the socket back to itself. To break the loop and make _nn_device_ function exit use linknanomsg:nn_term[3] function. RETURN VALUE ------------ The function loops until it hits an error. In such case it returns -1 and sets 'errno' to one of the values defined below. ERRORS ------ *EBADF*:: One of the provided sockets is invalid. *EINVAL*:: Either one of the socket is not an AF_SP_RAW socket; or the two sockets don't belong to the same protocol; or the directionality of the sockets doesn't fit (e.g. attempt to join two SINK sockets to form a device). *EINTR*:: The operation was interrupted by delivery of a signal. *ETERM*:: The library is terminating.

Structure 'nn_cmsghdr' represents a single ancillary property and contains following members: size_t cmsg_len; int cmsg_level; int cmsg_type; 'cmsg_len' is the size of the property data, including the preceding nn_cmsghdr structure. 'cmsg_level' is the level of the property; same values can be used as with linknanomsg:nn_getsockopt[3] and linknanomsg:nn_setsockopt[3]. 'cmsg_type' is the name of the property. These names are specific for each level. _NN_CMSG_FIRSTHDR_ returns a pointer to the first nn_cmsghdr in the control buffer in the supplied nn_msghdr structure. _NN_CMSG_NXTHDR_ returns the next nn_cmsghdr after the supplied nn_cmsghdr. Returns NULL if there isn't enough space in the buffer. _NN_CMSG_DATA_ returns a pointer to the data associated with supplied nn_cmsghdr. _NN_CMSG_SPACE_ returns the number of bytes occupied by nn_cmsghdr with payload of the specified length. _NN_CMSG_LEN_ returns the value to store in the cmsg_len member of the cmsghdr structure, taking into account any necessary alignment. EXAMPLE ------- Iterating over ancillary properties: ---- struct nn_cmsghdr *hdr = NN_CMSG_FIRSTHDR (&msg); while (hdr != NULL) { size_t len = hdr->cmsg_len - sizeof (nn_cmsghdr); printf ("level: %d property: %d length: %dB data: ", (int) hdr->cmsg_level, (int) hdr->cmsg_type, (int) len); unsigned char *data = NN_CMSG_DATA(hdr); while (len) { printf ("%02X", *data); ++data; --len; } printf ("\n"); hdr = NN_CMSG_NXTHDR (&msg, hdr); } ---- SEE ALSO -------- linknanomsg:nn_sendmsg[3] linknanomsg:nn_recvmsg[3] linknanomsg:nn_getsockopt[3] linknanomsg:nn_setsockopt[3] linknanomsg:nanomsg[7] AUTHORS ------- Martin Sustrik nanomsg-0.8-beta/doc/nn_poll.txt0000664000175000017500000000476512623652600017625 0ustar00travistravis00000000000000nn_poll(3) ========== NAME ---- nn_poll - poll a set of SP sockets for readability and/or writability SYNOPSIS -------- *#include * *int nn_poll (struct nn_pollfd *fds, int nfds, int timeout);* DESCRIPTION ----------- The function checks a set of SP socket and reports whether it's possible to send a message to the socket and/or receive a message from each socket. 'fds' argument is an array of nn_pollfd structures with 'nfds' argument specifying the size of the array: ---- struct nn_pollfd { int fd; short events; short revents; }; ---- Each entry in the array represents an SP socket to check. 'events' field specifies which events to check for. The value is a bitwise combination of the following values: *NN_POLLIN*:: Check whether at least one message can be received from the 'fd' socket without blocking. *NN_POLLOUT*:: Check whether at least one message can be sent to the 'fd' socket without blocking. After the function returns, 'revents' field contains bitwise combination of NN_POLLIN and NN_POLLOUT according to whether the socket is readable or writable. 'timeout' parameter specifies how long (in milliseconds) should the function block if there are no events to report. RETURN VALUE ------------ Upon successful completion, the number of nn_pollfds structures with events signaled is returned. In case of timeout, return value is 0. In case of error, -1 is returned and 'errno' is set the one of the values below. ERRORS ------ *EBADF*:: Some of the provided sockets are invalid. *EINTR*:: The operation was interrupted by delivery of a signal before the message was sent. *ETERM*:: The library is terminating. NOTE ---- nn_poll is a convenience function. You can achieve same behaviour by using NN_RCVFD and NN_SNDFD socket options. However, using the socket options allows for usage that's not possible with nn_poll, such as simultaneous polling for both SP and OS-level sockets, integration of SP sockets with external event loops etc. EXAMPLE ------- ---- struct nn_pollfd pfd [2]; pfd [0].fd = s1; pfd [0].events = NN_POLLIN | NN_POLLOUT; pfd [1].fd = s2; pfd [1].events = NN_POLLIN; rc = nn_poll (pfd, 2, 2000); if (rc == 0) { printf ("Timeout!"); exit (1); } if (rc == -1) { printf ("Error!"); exit (1); } if (pfd [0].revents & NN_POLLIN) { printf ("Message can be received from s1!"); exit (1); } ---- SEE ALSO -------- linknanomsg:nn_socket[3] linknanomsg:nn_getsockopt[3] linknanomsg:nanomsg[7] AUTHORS ------- Martin Sustrik nanomsg-0.8-beta/doc/nanomsg.txt0000664000175000017500000000462712623652600017623 0ustar00travistravis00000000000000nanomsg(7) ========== NAME ---- nanomsg - scalability protocols library SYNOPSIS -------- *cc* ['flags'] 'files' *-lnanomsg* ['libraries'] DESCRIPTION ----------- Following functions are exported by nanomsg library: Create an SP socket:: linknanomsg:nn_socket[3] Close an SP socket:: linknanomsg:nn_close[3] Set a socket option:: linknanomsg:nn_setsockopt[3] Retrieve a socket option:: linknanomsg:nn_getsockopt[3] Add a local endpoint to the socket:: linknanomsg:nn_bind[3] Add a remote endpoint to the socket:: linknanomsg:nn_connect[3] Remove an endpoint from the socket:: linknanomsg:nn_shutdown[3] Send a message:: linknanomsg:nn_send[3] Receive a message:: linknanomsg:nn_recv[3] Fine-grained alternative to nn_send:: linknanomsg:nn_sendmsg[3] Fine-grained alternative to nn_recv:: linknanomsg:nn_recvmsg[3] Allocation of messages:: linknanomsg:nn_allocmsg[3] linknanomsg:nn_reallocmsg[3] linknanomsg:nn_freemsg[3] Manipulation of message control data:: linknanomsg:nn_cmsg[3] Multiplexing:: linknanomsg:nn_poll[3] Retrieve the current errno:: linknanomsg:nn_errno[3] Convert an error number into human-readable string:: linknanomsg:nn_strerror[3] Query the names and values of nanomsg symbols:: linknanomsg:nn_symbol[3] Query properties of nanomsg symbols:: linknanomsg:nn_symbol_info[3] Start a device:: linknanomsg:nn_device[3] Notify all sockets about process termination:: linknanomsg:nn_term[3] Environment variables that influence nanomsg work:: linknanomsg:nn_env[7] Following scalability protocols are provided by nanomsg: One-to-one protocol:: linknanomsg:nn_pair[7] Request/reply protocol:: linknanomsg:nn_reqrep[7] Publish/subscribe protocol:: linknanomsg:nn_pubsub[7] Survey protocol:: linknanomsg:nn_survey[7] Pipeline protocol:: linknanomsg:nn_pipeline[7] Message bus protocol:: linknanomsg:nn_bus[7] Following transport mechanisms are provided by nanomsg: In-process transport:: linknanomsg:nn_inproc[7] Inter-process transport:: linknanomsg:nn_ipc[7] TCP transport:: linknanomsg:nn_tcp[7] TCPMUX transport:: linknanomsg:nn_tcpmux[7] WebSocket transport:: linknanomsg:nn_ws[7] Following tools are installed with the library: nanocat:: linknanomsg:nanocat[1] tcpmuxd:: linknanomsg:tcpmuxd[1] AUTHORS ------- Martin Sustrik nanomsg-0.8-beta/doc/nn_pair.txt0000664000175000017500000000303412623652600017576 0ustar00travistravis00000000000000nn_pair(7) ========== NAME ---- nn_pair - one-to-one scalability protocol SYNOPSIS -------- *#include * *#include * DESCRIPTION ----------- Pair protocol is the simplest and least scalable scalability protocol. It allows scaling by breaking the application in exactly two pieces. For example, if a monolithic application handles both accounting and agenda of HR department, it can be split into two applications (accounting vs. HR) that are run on two separate servers. These applications can then communicate via PAIR sockets. The downside of this protocol is that its scaling properties are very limited. Splitting the application into two pieces allows to scale the two servers. To add the third server to the cluster, application has to be split once more, say by separating HR functionality into hiring module and salary computation module. Whenever possible, try to use one of the more scalable protocols instead. Socket Types ~~~~~~~~~~~~ NN_PAIR:: Socket for communication with exactly one peer. Each party can send messages at any time. If the peer is not available or send buffer is full subsequent calls to linknanomsg:nn_send[3] will block until it's possible to send the message.

Please note that request/reply applications should be stateless. It's important to include all the information necessary to process the request in the request itself, including information about the sender or the originator of the request if this is necessary to respond to the request. Sender information cannot be retrieved from the underlying socket connection since, firstly, transports like IPC may not have a firm notion of a message origin. Secondly, transports that have some notion may not have a reliable one -- a TCP disconnect may mean a new sender, or it may mean a temporary loss in network connectivity. For this reason, sender information must be included by the application if required. Allocating 6 randomly-generated bytes in the message for the lifetime of the connection is sufficient for most purposes. For longer-lived applications, an UUID is more suitable. Socket Types ~~~~~~~~~~~~ NN_REQ:: Used to implement the client application that sends requests and receives replies. NN_REP:: Used to implement the stateless worker that receives requests and sends replies. Socket Options ~~~~~~~~~~~~~~ NN_REQ_RESEND_IVL:: This option is defined on the full REQ socket. If reply is not received in specified amount of milliseconds, the request will be automatically resent. The type of this option is int. Default value is 60000 (1 minute).

Messages are sent from NN_PUB sockets and will only be received by NN_SUB sockets that have subscribed to the matching 'topic'. Topic is an arbitrary sequence of bytes at the beginning of the message body. The NN_SUB socket will determine whether a message should be delivered to the user by comparing the subscribed topics (using NN_SUB_SUBSCRIBE on a full SUB socket) to the bytes initial bytes in the incomming message, up to the size of the topic. ---- nn_setsockopt (s, NN_SUB, NN_SUB_SUBSCRIBE, "Hello", 5); ---- Will match any message with intial 5 bytes being "Hello", for example, message "Hello, World!" will match. Topic with zero length matches any message. If the socket is subscribed to multiple topics, message matching any of them will be delivered to the user. Since the filtering is performed on the Subscriber side, all the messages from Publisher will be sent over the transport layer. The entire message, including the topic, is delivered to the user. Socket Types ~~~~~~~~~~~~ NN_PUB:: This socket is used to distribute messages to multiple destinations. Receive operation is not defined. NN_SUB:: Receives messages from the publisher. Only messages that the socket is subscribed to are received. When the socket is created there are no subscriptions and thus no messages will be received. Send operation is not defined on this socket. Socket Options ~~~~~~~~~~~~~~ NN_SUB_SUBSCRIBE:: Defined on full SUB socket. Subscribes for a particular topic. Type of the option is string. A single NN_SUB socket can handle multiple subscriptions.

In-process address is an arbitrary case-sensitive string preceded by 'inproc://' protocol specifier. All in-process addresses are visible from any module within the process. They are not visible from outside of the process. The nature of in-process transport makes it easy to pass pointers between threads instead of actual data. This is, however, considered a bad application design and violates the scalable share-nothing architecture. If you do pass pointers among threads, synchronising thread access to shared data becomes your responsibility. Such design also prevents moving the thread into different process or machine once the need arises. As a rule of the thumb, don't pass pointers among threads unless you know what you are doing. The overall buffer size for an inproc connection is determined by NN_RCVBUF socket option on the receiving end of the connection. NN_SNDBUF socket option is ignored. In addition to the buffer, one message of arbitrary size will fit into the buffer. That way, even messages larger than the buffer can be transfered via inproc connection.

The implementation uses native IPC mechanism provided by the local operating system and the IPC addresses are thus OS-specific. On POSIX-compliant systems, UNIX domain sockets are used and IPC addresses are file references. Note that both relative (ipc://test.ipc) and absolute (ipc:///tmp/test.ipc) paths may be used. Also note that access rights on the IPC files must be set in such a way that the appropriate applications can actually use them. On Windows, named pipes are used for IPC. IPC address is an arbitrary case-insensitive string containing any character except for backslash. Internally, address ipc://test means that named pipe \\.\pipe\test will be used.

TCP is the most widely used transport protocol, it is virtually ubiquitous and thus the transport of choice for communication over the network. When binding a TCP socket address of the form tcp://interface:port should be used. Port is the TCP port number to use. Interface is one of the following (optionally placed within square brackets): * Asterisk character (*) meaning all local network interfaces. * IPv4 address of a local network interface in numeric form (192.168.0.111). * IPv6 address of a local network interface in numeric form (::1). When connecting a TCP socket address of the form tcp://interface;address:port should be used. Port is the TCP port number to use. Interface is optional and specifies which local network interface to use. If not specified, OS will select an appropriate interface itself. If specified it can be one of the following (optionally placed within square brackets): * IPv4 address of a local network interface in numeric form (192.168.0.111). * IPv6 address of a local network interface in numeric form (::1). Finally, address specifies the remote address to connect to. It can be one of the following (optionally placed within square brackets): * IPv4 address of a remote network interface in numeric form (192.168.0.111). * IPv6 address of a remote network interface in numeric form (::1). * The DNS name of the remote box.

TCPMUX transport is basically the same as TCP transport (see linknanomsg:nn_tcp[7]) except that it allows to specify service names along with IP addresses and TCP ports. What it means in practice is that many applications on the same box can share the same TCP port. When connecting and binding use the same connection string syntax as with TCP transport, except that the initial protocol specification should be 'tcpmux://' instead of 'tcp://' and that the connection string should end with a slash and a service name: ---- nn_connect (s, "tcpmux://192.168.0.1:5555/foo"); ---- When binding to a TCPMUX endpoint, linknanomsg:nn_tcpmuxd[1] daemon must be running on the box and specified port.

This information is not available via the nanomsg API afterwards, however. Likewise, this implementation does not examine or use either any path or query parameters that may be supplied to `nn_bind()`, as it only binds to the TCP port. This implementation acts as a limited HTTP server that offers SP over WebSocket at all URIs for the given TCP address. Applications should not however depends on this behavior; intervening infrastructure may proxy, filter or route based on URI, and other implementations of the SP over WebSocket protocol may offer other HTTP services at the same TCP port, utilizing the path, query parameters, or both to determine the service to be used. Socket Options ~~~~~~~~~~~~~~ NN_WS_MSG_TYPE:: This option may be set to NN_WS_MSG_TYPE_TEXT or NN_WS_MSG_TYPE_BINARY. The value of this determines whether data messages are sent as WebSocket text frames, or binary frames, per RFC 6455. Text frames should contain only valid UTF-8 text in their payload, or they will be rejected. Binary frames may contain any data. Not all WebSocket implementations support binary frames. The default is to send binary frames. + This option may also be specified as control data when when sending a message with `nn_sendmsg()`. TODO: NN_TCP_NODELAY:: This option, when set to 1, disables Nagle's algorithm. It also disables delaying of TCP acknowledgments. Using this option improves latency at the expense of throughput. Type of this option is int. Default value is 0.

Please, do not try to parse output and do not build business logic based on it. NN_PRINT_ERRORS:: If set to non-empty string nanomsg will print errors to stderr. Some errors will be resolved by nanomsg itself (e.g. if nanomsg can't establish connection it will retry again in a moment). Some depend on the environment (e.g. port that is bound by another process need to be released). In any case nanomsg will not repeat the error message until error is clear and appear again (e.g. connection established then broken again). NN_PRINT_STATISTICS:: If set to non-empty string nanomsg will print some statistics to stderr. That's statistics is intended for debugging purposes only. NN_STATISTICS_SOCKET:: The nanomsg address to send statistics to. Nanomsg opens NN_PUB socket and sends statistics there. The data is sent using ESTP protocol. NOTES ----- The output of both debugging facilities (NN_PRINT_ERRORS, NN_PRINT_STATISTICS) is intended for reading by human and a subject for change at any time (even after 1.0 release). The NN_STATISTICS_SOCKET facility is intended to use by system administrators to debug network and application issues. The ESTP format is stable. But the nanomsg support of it is experimental and is subject to change or removal until 1.0 release. Anyway, there is *no excuse* for making application logic based on the data described here. And by application logic we mean any of the following: * Load balancing * Failover * Routing requests * Executing nn_connect/nn_bind There are other ways for load-balancing and failover in nanomsg. If you feel you can't do something, consider ask on the mailing list first.

It # sets the PTHREAD_LIBS output variable to the threads library and linker # flags, and the PTHREAD_CFLAGS output variable to any special C compiler # flags that are needed. (The user can also force certain compiler # flags/libs to be tested by setting these environment variables.) # # Also sets PTHREAD_CC to any special C compiler that is needed for # multi-threaded programs (defaults to the value of CC otherwise). (This # is necessary on AIX to use the special cc_r compiler alias.) # # NOTE: You are assumed to not only compile your program with these flags, # but also link it with them as well. e.g. you should link with # $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS # # If you are only building threads programs, you may wish to use these # variables in your default LIBS, CFLAGS, and CC: # # LIBS="$PTHREAD_LIBS $LIBS" # CFLAGS="$CFLAGS $PTHREAD_CFLAGS" # CC="$PTHREAD_CC" # # In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant # has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name # (e.g. PTHREAD_CREATE_UNDETACHED on AIX). # # Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the # PTHREAD_PRIO_INHERIT symbol is defined when compiling with # PTHREAD_CFLAGS. # # ACTION-IF-FOUND is a list of shell commands to run if a threads library # is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it # is not found. If ACTION-IF-FOUND is not specified, the default action # will define HAVE_PTHREAD. # # Please let the authors know if this macro fails on any platform, or if # you have any other suggestions or comments. This macro was based on work # by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help # from M. Frigo), as well as ac_pthread and hb_pthread macros posted by # Alejandro Forero Cuervo to the autoconf macro repository. We are also # grateful for the helpful feedback of numerous users. # # Updated for Autoconf 2.68 by Daniel Richard G. # # LICENSE # # Copyright (c) 2008 Steven G.
