| * TEST IDENTIFIER : getrlimit02 |
| * |
| * EXECUTED BY : anyone |
| * |
| * TEST TITLE : test for checking error conditions for getrlimit(2) |
| * |
| * TEST CASE TOTAL : 2 |
| * |
| * AUTHOR : Suresh Babu V. <suresh.babu@wipro.com> |
| * |
| * SIGNALS |
| * Uses SIGUSR1 to pause before test if option set. |
| * (See the parse_opts(3) man page). |
| * |
| * DESCRIPTION |
| * Verify that, |
| * 1) getrlimit(2) returns -1 and sets errno to EFAULT if an invalid |
| * address is given for address parameter. |
| * 2) getrlimit(2) returns -1 and sets errno to EINVAL if an invalid |
| * resource type (RLIM_NLIMITS is a out of range resource type) is |
| * passed. |
| * |
| * Setup: |
| * Setup signal handling. |
| * Pause for SIGUSR1 if option specified. |
| * |
| * Test: |
| * Loop if the proper options are given. |
| * Execute system call |
| * Check return code, if system call failed and errno set == expected errno |
| * Issue sys call fails with expected return value and errno. |
| * Otherwise, |
| * Issue sys call failed to produce expected error. |
| * |
| * Cleanup: |
| * Print errno log and/or timing stats if options given |
| * |
| * USAGE: <for command-line> |
| * getrlimit02 [-c n] [-e] [-i n] [-I x] [-P x] [-p] [-t] [-h] |
| * 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. |
| * -p : Pause for SIGUSR1 before startingt |
| * -t : Turn on syscall timing. |
| * -h : Display usage information. |
