PCAP_OPEN_OFFLINE(3PCAP)PCAP_OPEN_OFFLINE(3PCAP)NAME
pcap_open_offline, pcap_fopen_offline - 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_fopen_offline(FILE *fp, char *errbuf);
DESCRIPTIONpcap_open_offline() is called to open a ``savefile'' for reading.
fname specifies the name of the file to open. The file has the same
format as those used by tcpdump(1) and tcpslice(1). The name "-" in a
synonym for stdin.
Alternatively, you may call pcap_fopen_offline() to read dumped data
from an existing open stream fp. Note that on Windows, that stream
should be opened in binary mode.
RETURN VALUEpcap_open_offline() and pcap_fopen_offline() return a pcap_t * on suc‐
cess 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.
