| /* | ||
| * Test Name: mknod09 | ||
| * | ||
| * Test Description: | ||
| * Verify that, mknod() fails with -1 and sets errno to EINVAL if the mode is | ||
| * different than a normal file, device special file or FIFO. | ||
| * | ||
| * Expected Result: | ||
| * mknod() should fail with return value -1 and sets expected errno. | ||
| * | ||
| * Algorithm: | ||
| * Setup: | ||
| * Setup signal handling. | ||
| * Check id is super/root | ||
| * Pause for SIGUSR1 if option specified. | ||
| * Create temporary directory. | ||
| * | ||
| * Test: | ||
| * Loop if the proper options are given. | ||
| * Execute system call | ||
| * Check return code, if system call failed (return=-1) | ||
| * if errno set == expected errno | ||
| * Issue sys call fails with expected return value and errno. | ||
| * Otherwise, | ||
| * Issue sys call fails with unexpected errno. | ||
| * Otherwise, | ||
| * Issue sys call returns unexpected value. | ||
| * | ||
| * Cleanup: | ||
| * Print errno log and/or timing stats if options given | ||
| * Delete the temporary directory created. | ||
| * | ||
| * Usage: <for command-line> | ||
| * mknod09 [-c n] [-e] [-f] [-i n] [-I x] [-P x] [-t] | ||
| * where, -c n : Run n copies concurrently. | ||
| * -e : Turn on errno logging. | ||
| * -f : Turn off functionality Testing. | ||
| * -i n : Execute test n times. | ||
| * -I x : Execute test for x seconds. | ||
| * -P x : Pause for x seconds between iterations. | ||
| * -t : Turn on syscall timing. | ||
| * | ||
| * HISTORY | ||
| * 05/2002 Ported by André Merlier | ||
| * | ||
| * RESTRICTIONS: | ||
| * This test should be run by 'super-user' (root) only. | ||
