| 15 | * Test Name: getresgid01 |
| 16 | * |
| 17 | * Test Description: |
| 18 | * Verify that getresgid() will be successful to get the real, effective |
| 19 | * and saved user id of the calling process. |
| 20 | * |
| 21 | * Expected Result: |
| 22 | * getresgid() should return with 0 value and the real/effective/saved |
| 23 | * user ids should be equal to that of calling process. |
| 24 | * |
| 25 | * Algorithm: |
| 26 | * Setup: |
| 27 | * Setup signal handling. |
| 28 | * Pause for SIGUSR1 if option specified. |
| 29 | * |
| 30 | * Test: |
| 31 | * Loop if the proper options are given. |
| 32 | * Execute system call |
| 33 | * Check return code, if system call failed (return=-1) |
subrata_modak | 56207ce | 2009-03-23 13:35:39 +0000 | [diff] [blame] | 34 | * Log the errno and Issue a FAIL message. |

| 40 | * Issue Functionality-Fail message. |
| 41 | * Cleanup: |
| 42 | * Print errno log and/or timing stats if options given |
| 43 | * |
| 44 | * Usage: <for command-line> |
| 45 | * getresgid01 [-c n] [-f] [-i n] [-I x] [-P x] [-t] |
| 46 | * where, -c n : Run n copies concurrently. |
| 47 | * -f : Turn off functionality Testing. |
| 48 | * -i n : Execute test n times. |
| 49 | * -I x : Execute test for x seconds. |
| 50 | * -P x : Pause for x seconds between iterations. |
| 51 | * -t : Turn on syscall timing. |
