| * TEST IDENTIFIER : fcntl23 |
| * |
| * EXECUTED BY : anyone |
| * |
| * TEST TITLE : Basic test for fcntl(2) using F_SETLEASE & F_RDLCK argument. |
| * |
| * TEST CASE TOTAL : 1 |
| * |
| * WALL CLOCK TIME : 1 |
| * |
| * CPU TYPES : ALL |
| * |
| * AUTHOR : Robbie Williamson |
| * |
| * TEST CASES |
| * |
| * 1.) fcntl(2) returns...(See Description) |
| * |
| * INPUT SPECIFICATIONS |
| * The standard options for system call tests are accepted. |
| * (See the parse_opts(3) man page). |
| * |
| * OUTPUT SPECIFICATIONS |
| * |
| * DURATION |
| * Terminates - with frequency and infinite modes. |
| * |
| * SIGNALS |
| * Uses SIGUSR1 to pause before test if option set. |
| * (See the parse_opts(3) man page). |
| * |
| * RESOURCES |
| * None |
| * |
| * ENVIRONMENTAL NEEDS |
| * No run-time environmental needs. |
| * |
| * SPECIAL PROCEDURAL REQUIREMENTS |
| * None |
| * |
| * INTERCASE DEPENDENCIES |
| * None |
| * |
| * DETAILED DESCRIPTION |
| * This is a Phase I test for the fcntl(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 |
| * fcntl(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 |
| * |
