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.
