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.
