A BIF allows one to write arbitrary C++ code and access it via a function call inside a Zeek script. In this way, they can also be used to access parts of Zeek's internal C++ API that aren't already exposed via their own BIFs. At the moment, learning the format of a ``.bif`` file is likely easiest by just taking a look at the ``.bif`` files inside the Zeek source-tree. bifcl-1.6.0/COPYING000644 000765 000024 00000003457 14072107507 013600 0ustar00timstaff000000 000000 Copyright (c) 1995-2018, The Regents of the University of California through the Lawrence Berkeley National Laboratory and the International Computer Science Institute.
