What are you talking about? Where did you see that?

VarPtr() is for returning the address of the data held by a variable. The only case where this address matches the contents of a structure is for structures embedded into an object.

Otherwise, structures are Gambas object, and so their address is different from the address of their contents.

Only 'Object.Data()' can return the contents of a Gambas object, according to if it is a structure or not, or something else.

I don't understand what you are talking about with 'memcpy'.
