PCAP_FILE(3PCAP)														  PCAP_FILE(3PCAP)

NAME
pcap_file - get the standard I/O stream for a savefile being read 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 net- work 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().

PCAP_DUMP_OPEN(3PCAP)													     PCAP_DUMP_OPEN(3PCAP)

NAME
pcap_dump_open, pcap_dump_fopen - open a file to which to write packets SYNOPSIS
#include <pcap/pcap.h> pcap_dumper_t *pcap_dump_open(pcap_t *p, const char *fname); pcap_dumper_t *pcap_dump_fopen(pcap_t *p, FILE *fp); DESCRIPTION
pcap_dump_open() is called to open a ``savefile'' for writing. fname specifies the name of the file to open. The file will have the same format as those used by tcpdump(1) and tcpslice(1). The name "-" in a synonym for stdout. pcap_dump_fopen() is called to write data to an existing open stream fp. Note that on Windows, that stream should be opened in binary mode. p is a capture or ``savefile'' handle returned by an earlier call to pcap_create() and activated by an earlier call to pcap_activate(), or returned by an earlier call to pcap_open_offline(), pcap_open_live(), or pcap_open_dead(). The link-layer type and snapshot length from p are used as the link-layer type and snapshot length of the output file. RETURN VALUES
A pointer to a pcap_dumper_t structure to use in subsequent pcap_dump() and pcap_dump_close() calls is returned on success. NULL is returned on failure. If NULL is returned, pcap_geterr(p) can be used to get the error text. SEE ALSO
