+** Purpose:
+** Test to see that you can copy a portion of a string into a new buffer.
+** Also check that the strncpy function doesn't overflow when it is used.
+** Finally check that if the number of characters given is greater than the
+** amount to copy, that the destination buffer is padded with NULLs.
