NAME

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

SYNOPSIS

       #include <pcap/pcap.h>

       int pcap_set_tstamp_type(pcap_t *p, int tstamp_type);

DESCRIPTION

       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

       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).

BACKWARD COMPATIBILITY

       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.
