| * TEST IDENTIFIER : fcntl07 |
| * |
| * EXECUTED BY : anyone |
| * |
| * TEST TITLE : Close-On-Exec functional test |
| * |
| * PARENT DOCUMENT : none |
| * |
| * TEST CASE TOTAL : 2 |
| * |
| * WALL CLOCK TIME : 5 |
| * |
| * CPU TYPES : ALL |
| * |
| * AUTHOR : Glen Overby |
| * |
| * CO-PILOT : William Roske |
| * |
| * DATE STARTED : 08/11/93 |
| * |
| * INITIAL RELEASE : UNICOS 7.0 |
| * |
| * TEST CASES |
| * |
| * 1.) test close-on-exec with a regular file |
| * 2.) test close-on-exec with a system pipe |
| * |
| * INPUT SPECIFICATIONS |
| * |
| * Standard arguments accepted by parse_opts(3). |
| * |
| * The -t (timing) and -e options apply to the fcntl(.., F_SETFD, ..) |
| * system call. |
| * |
| * -T fd : If this option is given, the program runs as "test_open", |
| * testing <fd> to see if it is open or not and exiting |
| * accordingly: |
| * 0 not open (EBADF from fcntl(..., F_GETFD, ...)) |
| * 3 no error from fcntl |
| * errno fcntl returned an error other than EBADF |
| * |
| * -F name : File to open. Must be an absolute path |
| * and the file must be writable; |
| * -n program: path to the 'test_open' program |
| * |
| * OUTPUT SPECIFICATIONS |
| * This test uses the cuts-style test_res format output consisting of: |
| * |
| * test-name PASS/FAIL/BROK message |
| * |
| * the message will tell what type of test and, if it failed, indicate |
| * what the failure was. |
| * |
| * DURATION |
| * Terminates |
| * |
| * SIGNALS |
| * None |
| * |
| * RESOURCES |
| * None |
| * |
| * ENVIRONMENTAL NEEDS |
| * No run-time environmental needs. |
| * |
| * If this test is not called with a full pathname, it must be able |
| * to find itself on $PATH |
| * |
| * INTERCASE DEPENDENCIES |
| * none |
| * |
| * DETAILED DESCRIPTION |
| * |
| * Setup: |
| * Setup signal handling. |
| * Create and make current a temporary directory. |
| * Open a regular file for writing |
| * Create a system pipe |
| * Create a named pipe and open it for writing |
| * |
| * Test: |
| * Set the file descriptor for close-on-exec |
| * Fork |
| * Child execlp's the program "test_open". |
| * If the exec fails, exit "2" |
| * Parent waits |
| * Report results. |
| * |
| * Cleanup: |
| * Close file and pipes |
| * Remove the temporary directory |
| * |
| * BUGS |
