PCAP_SET_TIMEOUT(3PCAP)                          PCAP_SET_TIMEOUT(3PCAP)

NAME         top

       pcap_set_timeout - set the packet buffer timeout for a not-yet-
       activated capture handle

SYNOPSIS         top

       #include <pcap/pcap.h>

       int pcap_set_timeout(pcap_t *p, int to_ms);

DESCRIPTION         top

       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 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         top

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