NAME

time - time functions for gawk

SYNOPSIS

@load "time"

time = gettimeofday()
ret = sleep(amount)

CAUTION

This extension is deprecated in favor of the timex extension in the gawkextlib project. In the next major release of gawk, loading it will issue a warning. It will be removed from the gawk distribution in the major release after the next one.

DESCRIPTION

The 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 sleeping 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"
