     NAME
	  XOPEN.os/time/clock -	report CPU time	used testset

     DESCRIPTION
	  Clock	tests the clock() subroutine interface for conformance
	  to the XSI System Interface Page:clock()

     TESTS
     Compliance
	  1    If XPG3 mode:
		   A call to clock() returns the amount	of CPU time
		   (in microseconds) used since	the first call to
		   clock() in the calling process.
	       Otherwise:
		   A call to clock() returns the amount	of CPU time
		   (in microseconds) used since	a time related to the
		   process invocation.

	  2    The time	reported by clock() is the sum of user and
	       system times of the calling process and terminated
	       child processes for which it has	obtained the wait
	       status.
	       This test is executed in	XPG3 mode only.

     OUTPUTS
     Tests:
	  1-2  Pass/Fail indication only.

     PARAMETERS
	  VSX_CLOCK_ERR	: is needed to obtain the percentage of
	  allowable error in the difference between the	detected and
	  expected return values.
