* 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.
