| * TEST IDENTIFIER : flock02 |
| * |
| * EXECUTED BY : anyone |
| * |
| * TEST TITLE : Error condition test for flock(2) |
| * |
| * TEST CASE TOTAL : 3 |
| * |
| * AUTHOR : Vatsal Avasthi <vatsal.avasthi@wipro.com> |
| * |
| * SIGNALS |
| * Uses SIGUSR1 to pause before test if option set. |
| * (See the parse_opts(3) man page). |
| * |
| * DESCRIPTION |
| * This test verifies that |
| * 1) flock(2) returns -1 and sets error number to EBADF |
| * if the file descriptor is invalid. |
| * 2) flock(2) returns -1 and sets error number to EINVAL |
| * if the argument operation does not include LOCK_SH,LOCK_EX,LOCK_UN.$ |
| * 3) flock(2) returns -1 and sets error number to EINVAL |
| * if an invalid combination of locking modes is used i.e LOCK_SH with LOCK_EX |
| * |
| * Setup: |
| * Setup signal handling. |
| * Pause for SIGUSR1 if option specified. |
| * Create a temporary directory and chdir to it. |
| * Create a temporary file |
| * |
| * Test: |
| * Loop if proper options are given. |
| * Execute system call |
| * Check return code, |
| * if system call failed (return == -1) and errno == expected_errno |
| * Issue system call fails with expected return value and error number |
| * else |
| * Issue system call failed to produce expected error. |
| * |
| * Cleanup: |
| * Print errno log and/or timing stats if options given |
| * Deletes temporary directory. |
| * |
| * USAGE: <for command-line> |
| * flock02 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f] [-p] |
| * where, -c n : Run n copies concurrently. |
| * -f : Turn off functional testing |
| * -e : Turn on errno logging. |
| * -h : Show help screen $ |
| * -i n : Execute test n times. |
| * -I x : Execute test for x seconds. |
| * -p : Pause for SIGUSR1 before starting |
| * -P x : Pause for x seconds between iterations. |
| * -t : Turn on syscall timing. |
