PCAP_OPEN_DEAD(3PCAP)													     PCAP_OPEN_DEAD(3PCAP)

NAME
pcap_open_dead - 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); DESCRIPTION
pcap_open_dead() is 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. linktype specifies the link-layer type for the pcap_t. snaplen specifies the snapshot length for the pcap_t. SEE ALSO

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 func- tions 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 precision 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(). SEE ALSO

Shopt -s histappend

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file. # When the shell exits, append to the history file instead of overwriting it shopt -s histappend (3 Replies)
