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.
