NAME

getclock − get current value of system-wide clock

SYNOPSIS

#include <sys/timers.h>

int getclock(int clock_type, struct timespec *tp);

DESCRIPTION

The getclock() function gets the current value tp of the specified system-wide clock, clock_type. 

getclock() supports a clock_type of TIMEOFDAY, defined in <sys/timers.h>, which represents the time-of-day clock for the system.  For this clock, the values returned by getclock() represent the amount of time since the Epoch. 

RETURN VALUE

Upon successful completion, getclock() returns a value of zero; otherwise it returns a value of −1 and sets errno to indicate the error. 

ERRORS

getclock() fails if any of the following conditions are encountered:

[EINVAL] clock_type does not specify a known system-wide clock. 

[EIO] An error occurred while accessing the clock device.
