NAME¶
pcap_geterr, pcap_perror - get or print libpcap error message text
SYNOPSIS¶
#include <pcap/pcap.h>
char *pcap_geterr(pcap_t *p);
void pcap_perror(pcap_t *p, char *prefix);
DESCRIPTION¶
pcap_geterr() returns the error text pertaining to the last pcap library
error.
NOTE: the pointer it returns will no longer point to a valid
error message string after the
pcap_t passed to it is closed; you must
use or copy the string before closing the
pcap_t.
pcap_perror() prints the text of the last pcap library error on
stderr, prefixed by
prefix.
