TIME(3am)                  GNU Awk Extension Modules                 TIME(3am)


       time - time functions for gawk


       @load "time"

       time = gettimeofday()
       ret = sleep(amount)


       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.


       The time extension adds two functions named gettimeofday() and sleep(),
       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.


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