NAMEtime - time functions for gawk
SYNOPSIS@load "time" time = gettimeofday() ret = sleep(amount)
DESCRIPTIONThe time extension adds two functions named gettimeofday() and sleep(), as follows. gettimeofday() This function returns the number of seconds since the Epoch as a floating-point value. It should have subsecond precision. It returns -1 upon error and sets ERRNO to indicate the problem. sleep(seconds) This function attempts to sleep for the given amount of seconds, which may include a fractional portion. If seconds is negative, or the attempt to sleep fails, then it returns -1 and sets ERRNO. Otherwise, the function should return 0 after sleep‐ ing for the indicated amount of time.
EXAMPLE@load "time" ... printf "It is now %g seconds since the Epoch\n", gettimeofday() printf "Pausing for a while... " ; sleep(2.5) ; print "done"
