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.
