.SH DESCRIPTION
.BR pcap_lib_version ()
returns a pointer to a string giving information about the version of
the libpcap library being used.  The string begins with the words "libpcap
version".  Then follows the version, which consists of three dot-separated
numbers and the optional "-PRE-GIT" suffix to indicate a development
snapshot, same as in the output of
.B "pcap-config --version"
in sufficiently recent libpcap releases.  After the version often follows
additional text to indicate particular features.  For example:
.IP "an old release, on any OS"
.RS
.nf
