@combie Yeah, but you are missing the bit that the OP originally, before erasing his/her posts, wanted to pass in and **create** a subset of **ANY** type of array. Not just a char array. Making things a bit more.. interesting.

Unfortunately, the code posted in #11 does not accomplish that goal as it only works for objects that are trivially copyable.
