PCAP_MAJOR_VERSION(3)					     Library Functions Manual					     PCAP_MAJOR_VERSION(3)

NAME

       pcap_major_version, pcap_minor_version - get the version number of a savefile

SYNOPSIS

       #include <pcap/pcap.h>

       int pcap_major_version(pcap_t *p);
       int pcap_minor_version(pcap_t *p);

DESCRIPTION

       If  p  refers  to  a  savefile,	pcap_major_version()  returns the major number of the file format of the savefile and pcap_minor_version()
       returns the minor number of the file format of the savefile.  The version number is stored in the header of the savefile.

       If p refers to a live capture, the values returned by pcap_major_version() and pcap_minor_version() are not meaningful.

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);

DESCRIPTION

       pcap_open_offline() is 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 pcap-ng file format, although not all pcap-ng	files  can
       be read.  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 VALUE

       pcap_open_offline() and pcap_fopen_offline() 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.
