| * NAME |
| * getcwd01 |
| * |
| * DESCRIPTION |
| * Testcase to test that getcwd(2) sets errno correctly. |
| * |
| * ALGORITHM |
| * Test 1: Call getcwd(2) with a buf pointing outside the address space of |
| * process, and a valid size, and expect EFAULT to be |
| * set in errno. |
| * Test 2: Call getcwd(2) with buf = NULL, size = -1, and expect ENOMEM |
| * to be set in errno. |
| * Test 3: Call getcwd(2) with a valid buf, and size = 0, and expect |
| * EINVAL to be set in errno. |
| * Test 4: Call getcwd(2) on the root directory, and set size to 1, expect |
| * ERANGE to be set in errno. |
| * |
| * USAGE: <for command-line> |
| * getcwd01 [-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. |
| * |

| * RESTRICTIONS |
| * NONE |
