.TH PCAP_SET_TIMEOUT 3PCAP "1 December 2015"
.SH NAME
pcap_set_timeout \- set the read timeout for a not-yet-activated
capture handle
.SH SYNOPSIS
.nf
.ft B
#include <pcap/pcap.h>
.LP
.ft B
int pcap_set_timeout(pcap_t *p, int to_ms);
.ft
.fi
.SH DESCRIPTION
.B pcap_set_timeout()
sets the read timeout that will be used on a capture handle when
the handle is activated to
.IR to_ms ,
which is in units of milliseconds.
.LP
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.
.SH RETURN VALUE
.B pcap_set_timeout()
returns 0 on success or
.B PCAP_ERROR_ACTIVATED
if called on a capture handle that has been activated.
