PCAP_SET_TSTAMP_TYPE(3PCAP)                      PCAP_SET_TSTAMP_TYPE(3PCAP)

NAME top

       pcap_set_tstamp_type  -  set the time stamp type to be used by a cap‐
       ture 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).

BACKWARD COMPATIBILITY top

       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.
