TIME(3am) GNU Awk Extension Modules TIME(3am)
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. Loading it issues a warning. It will be removed
from the gawk distribution in the next major release.
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 re-
turns -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"
