- *	1.) write(2) returns...(See Description)
- *
- *    INPUT SPECIFICATIONS
- *	The standard options for system call tests are accepted.
- *	(See the parse_opts(3) man page).
- *
- *    OUTPUT SPECIFICATIONS
- *
- *    DURATION
- *	Terminates - with frequency and infinite modes.
- *
- *    SIGNALS
- *	Uses SIGUSR1 to pause before test if option set.
- *	(See the parse_opts(3) man page).
- *
- *    RESOURCES
- *	None

- *      No run-time environmental needs.

- *
- *    DETAILED DESCRIPTION
- *	This is a Phase I test for the write(2) system call.  It is intended
- *	to provide a limited exposure of the system call, for now.  It
- *	should/will be extended when full functional tests are written for
- *	write(2).
- *
- *	Setup:
- *	  Setup signal handling.
- *	  Pause for SIGUSR1 if option specified.
- *
- *	Test:
- *	 Loop if the proper options are given.
- *	  Execute system call
- *	  Check return code, if system call failed (return=-1)
- *		Log the errno and Issue a FAIL message.
- *	  Otherwise, Issue a PASS message.
- *
- *	Cleanup:
- *	  Print errno log and/or timing stats if options given
- *
- *    UPDATE HISTORY
- *      user     date  description
- *      ------------------------------------------------------
- *      wermager 3/00  Switched sequence of calls to TEST_PAUSE
- *                     and tst_tmpdir() in setup().$
