system interface for user-level packet capture
libpcap (Packet CAPture) provides a portable framework for low-level network monitoring. Applications include network statistics collection, security monitoring, network debugging, etc.
Since almost every system vendor provides a different interface for packet capture, and since there are several tools that require this functionality, 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.
