Name
pcap_geterr — Prototype: char *pcap_geterr(pcap_t *p)
Synopsis
Purpose: pcap_geterr returns the error text for
the last libpcap error that has occurred. This
requires that the pcap_t handle
p has not been closed using
pcap_close. pcap_geterr is used
to obtain human-readable error messages for all
libpcap functions that do not supply this
ability through the use of an errbuf parameter.
