Package libpcap-devel

Libraries and header files for the libpcap library

http://www.tcpdump.org

Libpcap provides a portable framework for low-level network
monitoring. Libpcap can provide network statistics collection,
security monitoring and network debugging. Since almost every system
vendor provides a different interface for packet capture, the libpcap
authors created this system-independent API to ease in porting and to
alleviate the need for several system-dependent packet capture modules
in each application.

This package provides the libraries, include files, and other
resources needed for developing libpcap applications.
