22 .TH PCAP_FILE 3PCAP "5 April 2008"
24 pcap_file \- get the standard I/O stream for a savefile being read
28 #include <pcap/pcap.h>
32 FILE *pcap_file(pcap_t *p);
37 returns the standard I/O stream of the ``savefile,'' if a ``savefile''
39 .BR pcap_open_offline() ,
40 or NULL, if a network device was opened with
45 .BR pcap_open_live() .
47 Note that the Packet Capture library is usually built with large file
48 support, so the standard I/O stream of the ``savefile'' might refer to
49 a file larger than 2 gigabytes; applications that use
51 should, if possible, use calls that support large files on the return
54 or the value returned by
56 when passed the return value of
59 pcap(3PCAP), pcap_open_offline(3PCAP)
