time - time functions for gawk
time = gettimeofday()
ret = sleep(amount)
extension adds two functions named gettimeofday()
, as follows.
- 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.
- 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 sleeping for the indicated
amount of time.
printf "It is now %g seconds since the Epoch\n", gettimeofday()
printf "Pausing for a while... " ; sleep(2.5) ; print "done"
