| * NAME |
| * mkdir04 |
| * |
| * DESCRIPTION |
| * |
| * ALGORITHM |
| * Setup: |
| * Setup signal handling. |
| * Pause for SIGUSR1 if option specified. |
| * Create temporary directory. |
| * |
| * Test: |
| * Loop if the proper options are given. |
| * fork the first child |
| * set to be ltpuser1 |
| * create a dirctory tstdir1 with 0700 permission |
| * fork the second child |
| * set to ltpuser2 |
| * try to create a subdirectory tstdir2 under tstdir1 |
| * check the returnvalue, if succeeded (return=0) |
| * Log the errno and Issue a FAIL message. |
| * Otherwise, |
| * Verify the errno |
| * if equals to EACCES, |
| * Issue Pass message. |
| * Otherwise, |
| * Issue Fail message. |
| * Cleanup: |
| * Print errno log and/or timing stats if options given |
| * Delete the temporary directory created. |
| * USAGE |
| * mkdir04 [-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 |
| * 07/2001 Ported by Wayne Boyer |
| * |
| * RESTRICTIONS |
| * None. |
