PCAP_OPEN_DEAD(3)	   Library Functions Manual	     PCAP_OPEN_DEAD(3)

NAME
       pcap_open_dead,	pcap_open_dead_with_tstamp_precision  -	 open  a  fake
       pcap_t for compiling filters or opening a capture for output

SYNOPSIS
       #include	<pcap/pcap.h>

       pcap_t *pcap_open_dead(int linktype, int	snaplen);
       pcap_t *pcap_open_dead_with_tstamp_precision(int	linktype, int snaplen,
	   u_int precision);

DESCRIPTION
       pcap_open_dead()	and  pcap_open_dead_with_tstamp_precision()  are  used
       for creating a pcap_t structure to use when calling the other functions
       in libpcap.  It is typically used when just using libpcap for compiling
       BPF  code;  it can also be used if using	pcap_dump_open(), pcap_dump(),
       and pcap_dump_close() to	write a	savefile if there is  no  pcap_t  that
       supplies	the packets to be written.

       linktype	specifies the link-layer type for the pcap_t.

       snaplen specifies the snapshot length for the pcap_t.

       When pcap_open_dead_with_tstamp_precision(), is used to create a	pcap_t
       for use with pcap_dump_open(), precision	specifies the time stamp  pre-
       cision  for packets; PCAP_TSTAMP_PRECISION_MICRO	should be specified if
       the packets to be written have time stamps in seconds and microseconds,
       and PCAP_TSTAMP_PRECISION_NANO should be	specified if the packets to be
       written have time stamps	in seconds and nanoseconds.   Its  value  does
       not affect pcap_compile().
