pcap_set_timeout — set the read timeout for a not-yet-activated capture handle

Synopsis

#include <pcap/pcap.h>

int pcap_set_timeout(pcap_t *p, int to_ms);

Description

pcap_set_timeout() sets the read timeout that will be used on a capture handle when the handle is activated to to_ms, which is in units of milliseconds.

The behavior, if the timeout isn't specified, is undefined. We recommend always setting the timeout to a non-zero value unless immediate mode is set, in which case the timeout has no effect.

Return Value

pcap_set_timeout() returns 0 on success or PCAP_ERROR_ACTIVATED if called on a capture handle that has been activated.
