PCAP_SET_TIMEOUT(3PCAP) PCAP_SET_TIMEOUT(3PCAP)
NAME
pcap_set_timeout - set the packet buffer timeout for a not-yet-acti-
vated capture handle
SYNOPSIS
#include <pcap/pcap.h>
int pcap_set_timeout(pcap_t *p, int to_ms);
DESCRIPTION
pcap_set_timeout() sets the packet buffer timeout that will be used on
a capture handle when the handle is activated to to_ms, which is in
units of milliseconds. (See pcap(3PCAP) for an explanation of the
packet buffer timeout.)
The behavior, if the timeout isn't specified, is undefined, as is the
behavior if the timeout is set to zero or to a negative value. We rec-
ommend 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.
