pcap_set_tstamp_type(3pcap) — Linux manual page



NAME         top

       pcap_set_tstamp_type - set the time stamp type to be used by a
       capture device

SYNOPSIS         top

       #include <pcap/pcap.h>

       int pcap_set_tstamp_type(pcap_t *p, int tstamp_type);

DESCRIPTION         top

       pcap_set_tstamp_type() sets the type of time stamp desired for
       packets captured on the pcap descriptor to the type specified by
       tstamp_type.  It must be called on a pcap descriptor created by
       pcap_create(3PCAP) that has not yet been activated by
       pcap_activate(3PCAP).  pcap_list_tstamp_types(3PCAP) will give a
       list of the time stamp types supported by a given capture device.
       See pcap-tstamp(7) for a list of all the time stamp types.

RETURN VALUE         top

       pcap_set_tstamp_type() returns 0 on success if the specified time
       stamp type is expected to be supported by the capture device,
       PCAP_WARNING_TSTAMP_TYPE_NOTSUP if the specified time stamp type
       is not supported by the capture device, PCAP_ERROR_ACTIVATED if
       called on a capture handle that has been activated, and
       PCAP_ERROR_CANTSET_TSTAMP_TYPE if the capture device doesn't
       support setting the time stamp type (only older versions of
       libpcap will return that; newer versions will always allow the
       time stamp type to be set to the default type).


       This function became available in libpcap release 1.2.1.  In
       previous releases, the time stamp type cannot be set; only the
       default time stamp type offered by a capture source is available.
