- * NAME
- *	memcpy  --  test memcpy
- *
- * CALLS
- *	memcpy1(3)
- *
- * ALGORITHM
- *	There are 2 cases for copies:  S = Source, D = Destination
- *
- *	  1 - S < D no overlap
- *	  2 - D < S no overlap
+/*\
+ * [DESCRIPTION]
  *
- *	We try both cases.  Check buffer boundaries.
- *
- * RESTRICTIONS
+ * The testcase for buffer copy by check boundary conditions.
