| * NAME |
| * sysctl04.c |
| * |
| * DESCRIPTION |
| * Testcase to check that sysctl(2) sets errno to ENOTDIR |
| * |
| * ALGORITHM |
| * 1. Call sysctl(2) with sc_nlen set to 0, and expect ENOTDIR to be set. |
| * 2. Call sysctl(2) with sc_nlen greater than CTL_MAXNAME, and expect |
| * ENOTDIR to be set in the errno. |
| * |
| * USAGE: <for command-line> |
| * sysctl04 [-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 |
| * None |
