| * 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. |
| * |
