I have to create a DLL which is used by a VB6 application. This DLL has to provide several functions, some of them must return strings.
This is the VB6 declaration:
Declare Function MyProc Lib "mylib.dll" (ByVal Param As String) As String
And this the Delphi implementation stub in
function MyProc(AParam: PChar): PChar; stdcall;
ReturnValue := GetReturnValue(AParam);
Result := ???;
What do I have to return here? Who will free the memory of the returnd PChar string?
EDIT: I'm asking about Delphi 2005 (
