| /* |
| * Test Name: mknod07 |
| * |
| * Test Description: |
| * Verify that, |
| * 1) mknod(2) returns -1 and sets errno to EPERM if the process id of |
| * the caller is not super-user. |
| * 2) mknod(2) returns -1 and sets errno to EACCES if parent directory |
| * does not allow write permission to the process. |
| * |
| * Expected Result: |
| * mknod() should fail with return value -1 and set expected errno. |
| * |
| * Algorithm: |
| * Setup: |
| * Setup signal handling. |
| * Create temporary directory. |
| * 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) |
| * 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(s)/file(s) created. |
| * |
| * Usage: <for command-line> |
| * mknod07 [-c n] [-e] [-i n] [-I x] [-P x] [-t] |
| * where, -c n : Run n copies concurrently. |
| * -e : Turn on errno logging. |
| * -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 |
| * 07/2001 Ported by Wayne Boyer |
| * |
| * RESTRICTIONS: |
| * This test should be executed by non-super-user only. |
