pcap_major_version(3pcap) [osf1 man page]


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_ver- sion() returns the minor number of the file format of the ``savefile''. The version number is stored in the ``savefile''; note that the meaning of its values depends on the type of ``savefile'' (for example, pcap or pcap-NG). If p refers to a live capture, the values returned by pcap_major_version() and pcap_minor_version() are not meaningful. SEE ALSO

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. SEE ALSO
