PCAP_SET_TIMEOUT(3) Library Functions Manual PCAP_SET_TIMEOUT(3) NAME 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.
