time = gettimeofday()
ret = sleep(amount)
- 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.
@load "time" ... printf "It is now %g seconds since the Epoch\n", gettimeofday() printf "Pausing for a while... " ; sleep(2.5) ; print "done"
