-/*
- * NAME
- *	fcntl13.c
- *
- * DESCRIPTION
- *	Testcase to test that fcntl() sets errno correctly.
+/*\
+ * [Description]
  *
- * USAGE
- *	fcntl13
+ * Tests basic error handling of the fcntl syscall.
  *
- * HISTORY
- *	07/2001 Ported by Wayne Boyer
- *
- * RESTRICTIONS
- *	NONE
+ * - EFAULT when cmd argument is F_SETLK and the data pointed to by arg is not valid
+ * - EINVAL when cmd argument is not recognized by this kernel
+ * - EINVAL when cmd argument is F_GETLK, F_SETLK, or F_SETLKW and fd does not support locking
+ * - EBADF when fd refers to an invalid file descriptor
