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.
