- * NAME
- *	shmdt02.c
- *
- * DESCRIPTION
- *	shmdt02 - check for EINVAL error
- *
- * ALGORITHM
- *	loop if that option was specified
- *	  call shmdt() using an invalid shared memory address
- *	  check the errno value
- *	    issue a PASS message if we get EINVAL
- *	  otherwise, the tests fails
- *	    issue a FAIL message
- *	call cleanup
+/*\
+ * [Description]
  *
- * USAGE:  <for command-line>
- *  shmdt02 [-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.
+ * Tests basic error handing of the shmdt syscall.
  *
- * HISTORY
- *	03/2001 - Written by Wayne Boyer
- *
- * RESTRICTIONS
- *	none
+ * -EINVAL there is no shared memory segment attached at shmaddr.
+ * -EINVAL shmaddr is not aligned on a page boundary.
