pcap_dump_open, pcap_dump_fopen - open a file to which to write packets SYNOPSIS
#include <pcap/pcap.h> pcap_dumper_t *pcap_dump_open(pcap_t *p, const char *fname); pcap_dumper_t *pcap_dump_fopen(pcap_t *p, FILE *fp); DESCRIPTION
pcap_dump_open() is called to open a ``savefile'' for writing. fname specifies the name of the file to open. The file will have the same format as those used by tcpdump(1) and tcpslice(1). The name "-" in a synonym for stdout. pcap_dump_fopen() is called to write data to an existing open stream fp. Note that on Windows, that stream should be opened in binary mode. p is a capture or ``savefile'' handle returned by an earlier call to pcap_create() and activated by an earlier call to pcap_activate(), or returned by an earlier call to pcap_open_offline(), pcap_open_live(), or pcap_open_dead(). The link-layer type and snapshot length from p are used as the link-layer type and snapshot length of the output file. RETURN VALUES
A pointer to a pcap_dumper_t structure to use in subsequent pcap_dump() and pcap_dump_close() calls is returned on success. NULL is returned on failure. If NULL is returned, pcap_geterr(p) can be used to get the error text. 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)
