| 21 | * NAME |
| 22 | * sysctl01.c |
| 23 | * |
| 24 | * DESCRIPTION |
| 25 | * Testcase for testing the basic functionality of sysctl(2) system call. |
| 26 | * This testcase attempts to read the kernel parameters using |
| 27 | * sysctl({CTL_KERN, KERN_* }, ...) and compares it with the known |
| 28 | * values. |
| 29 | * |
| 30 | * USAGE: <for command-line> |
| 31 | * sysctl01 [-c n] [-f] [-i n] [-I x] [-P x] [-t] |
| 32 | * where, -c n : Run n copies concurrently. |
| 33 | * -f : Turn off functionality Testing. |
| 34 | * -i n : Execute test n times. |
| 35 | * -I x : Execute test for x seconds. |
| 36 | * -P x : Pause for x seconds between iterations. |
| 37 | * -t : Turn on syscall timing. |
| 38 | * |
