PCAP_GETERR(3) FreeBSD Library Functions Manual PCAP_GETERR(3)
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, const 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.
