PCAP_GETERR(3PCAP)                                    PCAP_GETERR(3PCAP)

NAME         top

       pcap_geterr, pcap_perror - get or print libpcap error message
       text

SYNOPSIS         top

       #include <pcap/pcap.h>

       char *pcap_geterr(pcap_t *p);
       void pcap_perror(pcap_t *p, const char *prefix);

DESCRIPTION         top

       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.
