PCAP_SET_TSTAMP_PRECISION(3PCAP)        PCAP_SET_TSTAMP_PRECISION(3PCAP)

НАЗВАНИЕ

       pcap_set_tstamp_precision - set the time stamp precision returned
       in captures

СИНТАКСИС

       #include <pcap/pcap.h>

       int pcap_set_tstamp_precision(pcap_t *p, int tstamp_precision);

ОПИСАНИЕ

       pcap_set_tstamp_precision() sets the precision of the time stamp
       desired for packets captured on the pcap descriptor to the type
       specified by tstamp_precision.  It must be called on a pcap
       descriptor created by pcap_create(3PCAP) that has not yet been
       activated by pcap_activate(3PCAP).  Two time stamp precisions are
       supported, microseconds and nanoseconds. One can use options
       PCAP_TSTAMP_PRECISION_MICRO and PCAP_TSTAMP_PRECISION_NANO to
       request desired precision. By default, time stamps are in
       microseconds.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       pcap_set_tstamp_precision() returns 0 on success if the specified
       time stamp precision is expected to be supported by the capture
       device, PCAP_ERROR_TSTAMP_PRECISION_NOTSUP if the capture device
       does not support the requested time stamp precision,
       PCAP_ERROR_ACTIVATED if called on a capture handle that has been
       activated.

СООТВЕТСТВИЕ С ПРЕДЫДУЩИМИ ВЕРСИЯМИ

       This function became available in libpcap release 1.5.1.  In
       previous releases, time stamps from a capture device or savefile
       are always given in seconds and microseconds.
