*
* TEST IDENTIFIER : mkdir01
*
* EXECUTED BY : anyone
*
* TEST TITLE : Basic errno test for mkdir(2)
*
* PARENT DOCUMENT : mkstds02
*
* TEST CASE TOTAL : 2
*
* WALL CLOCK TIME : 1
*
* CPU TYPES : ALL
*
* AUTHOR : Bill Branum
*
* CO-PILOT : Kathy Olmsted
*
* DATE STARTED : 4/15/92
*
* INITIAL RELEASE : UNICOS 7.0
*
* TEST CASES
*
* mkdir(2) test for errno(s) EFAULT.
*
* INPUT SPECIFICATIONS
* The standard options for system call tests are accepted.
* (See the parse_opts(3) man page).
*
* DURATION
* Terminates - with frequency and infinite modes.
*
* SIGNALS
* Uses SIGUSR1 to pause before test if option set.
* (See the parse_opts(3) man page).
*
* ENVIRONMENTAL NEEDS
* No run-time environmental needs.
*
* DETAILED DESCRIPTION
* This test will verify that mkdir(2) returns a value of
* -1 and sets errno to EFAULT when the path argument points
* outside (above/below) the allocated address space of the
* process.
*
* Setup:
* Setup signal handling.
* Create and make current a temporary directory.
* 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.
*
