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

pcap_open_offline, pcap_fopen_offline - open a saved capture file for reading
pcap_t *pcap_open_offline(const char *fname, char *errbuf);
pcap_t *pcap_fopen_offline(FILE *fp, char *errbuf);
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.
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.

I'm writing a short script to check if a continuous port is running on a server.

I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
