- * Description:
- * The testcase checks the various errnos of the unlink(2).
- * 1) unlink() returns ENOENT if file doesn't exist.
- * 2) unlink() returns ENOENT if path is empty.
- * 3) unlink() returns ENOENT if path contains a non-existent file.
- * 4) unlink() returns EFAULT if address is invalid.
- * 5) unlink() returns ENOTDIR if path contains a regular file.
- * 6) unlink() returns ENAMETOOLONG if path contains a regular file.
+/*\
+ * [Description]
+ *
+ * Verify that unlink() fails with
+ * - ENOENT when file does not exist
+ * - ENOENT when pathname is empty
+ * - ENOENT when a component in pathname does not exist
+ * - EFAULT when pathname points outside the accessible address space
+ * - ENOTDIR when a component used as a directory in pathname is not,
+ * in fact, a directory
+ * - ENAMETOOLONG when pathname is too long
