| 21 | * NAME |
| 22 | * sysctl04.c |
| 23 | * |
| 24 | * DESCRIPTION |
| 25 | * Testcase to check that sysctl(2) sets errno to ENOTDIR |
| 26 | * |
| 27 | * ALGORITHM |
| 28 | * 1. Call sysctl(2) with sc_nlen set to 0, and expect ENOTDIR to be set. |
| 29 | * 2. Call sysctl(2) with sc_nlen greater than CTL_MAXNAME, and expect |
| 30 | * ENOTDIR to be set in the errno. |
| 31 | * |
| 32 | * USAGE: <for command-line> |
| 33 | * sysctl04 [-c n] [-e] [-i n] [-I x] [-P x] [-t] |
| 34 | * where, -c n : Run n copies concurrently. |
| 35 | * -e : Turn on errno logging. |
| 36 | * -i n : Execute test n times. |
| 37 | * -I x : Execute test for x seconds. |
| 38 | * -P x : Pause for x seconds between iterations. |
| 39 | * -t : Turn on syscall timing. |
| 40 | * |
