.TH PCAP_SET_TIMEOUT 3PCAP "6 December 2017"
.SH NAME
pcap_set_timeout \- set the packet buffer 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
.BR pcap_set_timeout ()
sets the packet buffer timeout that will be used on a capture handle
when the handle is activated to
.IR to_ms ,
which is in units of milliseconds.  (See
.BR pcap (3PCAP)
for an explanation of the packet buffer timeout.)
.LP
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
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
.BR pcap_set_timeout ()
returns
.B 0
on success or
.B PCAP_ERROR_ACTIVATED
if called on a capture handle that has been activated.
