Hi Jos,

The RtlMoveMemory can be declared in many ways depending on what parameters are. Can you give more info about what you are trying to copy, preferebly with VFP code showing source of data to copy?
You can also check Heap allocation class File #9482 for existing declarations. maybe one fits your requirement.
