NAME
pcap_open_offline, pcap_open_offline_with_tstamp_precision,
pcap_fopen_offline, pcap_fopen_offline_with_tstamp_precision - open a
saved capture file for reading
SYNOPSIS
#include <pcap/pcap.h>
char errbuf[PCAP_ERRBUF_SIZE];
pcap_t *pcap_open_offline(const char *fname, char *errbuf);
pcap_t *pcap_open_offline_with_tstamp_precision(const char *fname,
u_int precision, char *errbuf);
pcap_t *pcap_fopen_offline(FILE *fp, char *errbuf);
pcap_t *pcap_fopen_offline_with_tstamp_precision(FILE *fp,
u_int precision, char *errbuf);
DESCRIPTION
pcap_open_offline() and pcap_open_offline_with_tstamp_precision() are
called to open a ``savefile'' for reading.
fname specifies the name of the file to open. The file can have the
pcap file format as described in pcap-savefile(5), which is the file
format used by, among other programs, tcpdump(1) and tcpslice(1), or
can have the pcapng file format, although not all pcapng files can be
read. The name "-" is a synonym for stdin.
pcap_open_offline_with_tstamp_precision() takes an additional precision
argument specifying the time stamp precision desired; if
PCAP_TSTAMP_PRECISION_MICRO is specified, packet time stamps will be
supplied in seconds and microseconds, and if PCAP_TSTAMP_PRECISION_NANO
is specified, packet time stamps will be supplied in seconds and
nanoseconds. If the time stamps in the file do not have the same pre‐
cision as the requested precision, they will be scaled up or down as
necessary before being supplied.
Alternatively, you may call pcap_fopen_offline() or pcap_fopen_off‐
line_with_tstamp_precision() to read dumped data from an existing open
stream fp. pcap_fopen_offline_with_tstamp_precision() takes an addi‐
tional precision argument as described above. Note that on Windows,
that stream should be opened in binary mode.
RETURN VALUE
pcap_open_offline(), pcap_open_offline_with_tstamp_precision(),
pcap_fopen_offline(), and pcap_fopen_offline_with_tstamp_precision()
return a pcap_t * on success and NULL on failure. If NULL is returned,
errbuf is filled in with an appropriate error message. errbuf is
assumed to be able to hold at least PCAP_ERRBUF_SIZE chars.
BACKWARD COMPATIBILITY
pcap_open_offline_with_tstamp_precision and pcap_fopen_off‐
line_with_tstamp_precision became available in libpcap release 1.5.1.
In previous releases, time stamps from a savefile are always given in
seconds and microseconds.
