SYNOPSIS


#include <pcap/pcap.h>


FILE *pcap_file(pcap_t *p);

DESCRIPTION

pcap_file() returns the standard I/O stream of the ‘‘savefile,’’ if a ‘‘savefile’’ was opened with pcap_open_offline(), or NULL, if a network device was opened with pcap_create() and pcap_activate(), or with pcap_open_live().

Note that the Packet Capture library is usually built with large file support, so the standard I/O stream of the ‘‘savefile’’ might refer to a file larger than 2 gigabytes; applications that use pcap_file() should, if possible, use calls that support large files on the return value of pcap_file() or the value returned by fileno() when passed the return value of pcap_file().
