A signal of the group HUP,INT,QUIT,TERM and USR1 tells multiwatch to go into "shutdown" mode, so it won't restart children after receiving it. .SH EXAMPLE .TP 8 Spawn 2 rails instances on the same FastCGI socket (and supervise them): .RS 8 .B spawn-fcgi -s /tmp/fastcgi-rails.sock -n -- /usr/bin/multiwatch -f 2 /home/rails/public/dispatch.fcgi .RE .SH SEE ALSO spawn-fcgi(1) .SH AUTHOR Stefan Buehler . multiwatch-1.0.0/multiwatch.c0000644000175000017500000001703711444646131013153 00000000000000 #include #include #include #include #include #include #include #include #include #ifdef HAVE_CONFIG_H #include "config.h" #endif #define UNUSED(x) ((void)(x)) #define PACKAGE_DESC (PACKAGE_NAME " v" PACKAGE_VERSION " - forks and watches multiple instances of a program in the same environment") typedef struct { gchar **app;
