*
* TEST IDENTIFIER : rmdir05
*
* EXECUTED BY : anyone
*
* TEST TITLE : Functionality Tests for rmdir(2)
*
* PARENT DOCUMENT : rmstds02
*
* TEST CASE TOTAL : 6
*
* WALL CLOCK TIME : 2
*
* CPU TYPES : ALL
*
* AUTHOR : Bill Branum
*
* CO-PILOT : Steve Shaw
*
* DATE STARTED : 4/23/92
*
* INITIAL RELEASE : UNICOS 7.0
*
* TEST CASES
* rmdir(2) test for errno(s) EINVAL, EMLINK, EFAULT
*
* INPUT SPECIFICATIONS
* The standard options for system call tests are accepted.
* (See the parse_opts(3) man page).
*
* ENVIRONMENTAL NEEDS
* No run-time environmental needs.
*
* DETAILED DESCRIPTION
* Verify that rmdir(2) returns a value of -1 and sets errno
* to indicate the error.
*
* Setup:
* Setup signal handling.
* Create a temporary directory and make it current.
* 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.
* If doing functional test
* check the errno returned and print result message
*
* Cleanup:
* Print errno log and/or timing stats if options given.
* Remove the temporary directory.
* Exit.
*
