NAME
pcap_lib_version - get the version information for libpcap
SYNOPSIS
#include <pcap/pcap.h>
pcap_lib_version(3)
DESCRIPTION
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" and a space. 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 pcap-config --version in sufficiently recent libpcap
releases. After the version often follow a space and additional text
in an arbitrary human-readable form to indicate particular features.
For example:
an old release, on any OS
libpcap version 1.5.3
a newer release on a Linux host
libpcap version 1.10.4 (with TPACKET_V3)
the same, built with DAG support only
libpcap version 1.10.4 (DAG-only)
a development snapshot on a FreeBSD host
libpcap version 1.11.0-PRE-GIT (64-bit time_t, with zerocopy and netmap support)
