| * TEST IDENTIFIER : alarm03 |
| * |
| * EXECUTED BY : anyone |
| * |
| * TEST TITLE : alarm(2) cleared by a fork |
| * |
| * PARENT DOCUMENT : usctpl01 |
| * |
| * TEST CASE TOTAL : 1 |
| * |
| * WALL CLOCK TIME : 1 |
| * |
| * CPU TYPES : ALL |
| * |
| * AUTHOR : Richard Logan |
| * |
| * CO-PILOT : Dennis Arason |
| * |
| * DATE STARTED : 08/96 |
| * |
| * |
| * TEST CASES |
| * |
| * 1.) alarm(100), fork, child's alarm(0) shall return 0; |
| * 2.) alarm(100), fork, parent's alarm(0) shall return non-zero. |
| * |
| * INPUT SPECIFICATIONS |
| * The standard options for system call tests are accepted. |
| * (See the parse_opts(3) man page). |
| * |
| * |
| * SPECIAL PROCEDURAL REQUIREMENTS |
| * None |
| * |
| * |
| * DETAILED DESCRIPTION |
| * This is a Phase I test for the alarm(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 |
| * alarm(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 |
| * |
