Sean,
I am puzzled by your response. The variable len is defined in a block,
and then the variable length is defined in a block within the scope of the
block where len is defined. By the rules of C, len should still contain the
value of (MemHandleSize(registroH)). I don't understand why defining length
in the outer scope as you recommend will cause the value of len to not be
lost.
