This implementation is not safe and is not following strncpy_s semantics.

It should ensure that \0 is always copied to the destination.

It should check for the case when count == _TRUNCATE, and handle it
appropriately (truncate the string if needed and return STRUNCATE). 

Please make it behave like described in
http://msdn.microsoft.com/en-us/library/5dae5d43(v=vs.80).aspx
