- * 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.
+ * Testcase to test that getcwd(2) sets errno correctly.
+ * 1) getcwd(2) fails if buf points to a bad address.
+ * 2) getcwd(2) fails if the size is invalid.
+ * 3) getcwd(2) fails if the size is set to 0.
+ * 4) getcwd(2) fails if the size is set to 1.
+ * 5) getcwd(2) fails if buf points to NULL and the size is set to 1.
*
- * 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.
+ * Expected Result:
+ * 1) getcwd(2) should return NULL and set errno to EFAULT.
+ * 2) getcwd(2) should return NULL and set errno to ENOMEM.
+ * 3) getcwd(2) should return NULL and set errno to EINVAL.
+ * 4) getcwd(2) should return NULL and set errno to ERANGE.
+ * 5) getcwd(2) should return NULL and set errno to ERANGE.
