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.
