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 .B "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: .IP "an old release, on any OS" .RS .nf .B libpcap version 1.5.3 .fi .RE .IP "a newer release on a Linux host" .RS .nf .B libpcap version 1.10.4 (with TPACKET_V3) .fi .RE .IP "the same, built with DAG support only" .RS .nf .B libpcap version 1.10.4 (DAG-only) .fi .RE .IP "a development snapshot on a FreeBSD host" .RS .nf .B libpcap version 1.11.0-PRE-GIT (64-bit time_t, with zerocopy and netmap support) .fi .RE .SH SEE ALSO .BR pcap\-config (1), .BR pcap (3PCAP)
