PCAP_SET_TSTAMP_PRECISION(3PCAP) PCAP_SET_TSTAMP_PRECISION(3PCAP) NAME pcap_set_tstamp_precision - set the time stamp precision returned in captures SYNOPSIS #include <pcap/pcap.h> int pcap_set_tstamp_precision(pcap_t *p, int tstamp_precision); DESCRIPTION pcap_set_tstamp_precision() sets the precision of the time stamp de- sired 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_acti- vate(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. RETURN VALUE 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 sup- port the requested time stamp precision, PCAP_ERROR_ACTIVATED if called on a capture handle that has been activated. BACKWARD COMPATIBILITY 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.
