- * NAME
- *	getsid01.c
- *
- * DESCRIPTION
- *	getsid01 - call getsid() and make sure it succeeds
- *
- * ALGORITHM
- *	loop if that option was specified
- *	issue the system call
- *	check the return value
- *	if return value == -1
- *	  issue a FAIL message, break remaining tests and cleanup
- *	if we are doing functional testing
- *	  save the return value from the getsid() call - the session ID
- *	  fork a child and get the child's session ID
- *	  if the child's session ID == the parent's session ID
- *	    issue a PASS message
- *	  else
- *	    issue a FAIL message
- *	else issue a PASS message
- *	call cleanup
- *
- * USAGE:  <for command-line>
- *  getsid01 [-c n] [-f] [-i n] [-I x] [-P x] [-t]
- *     where,  -c n : Run n copies concurrently.
- *             -f   : Turn off functionality Testing.
- *	       -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.
- *
- * HISTORY
- *	07/2001 Ported by Wayne Boyer
+/*\
+ * [Description]
  *
- * RESTRICTIONS
- *	none
+ * Verify that session IDs returned by getsid() (with argument pid=0)
+ * are same in parent and child process.
