However, like in my first mail, if I define THandler a procedure of
object, it makes easier to SetHandler(AMethod); but how can I use that
"procedure of object" pointer in the so?
It works the same, cast the data you receive to a TMethod and call the
"code" member with the appropriate parameters. So, in the "C" library do
this:
typedef struct
{
Data: Pointer;
Code: Pointer;
}TMethod;
void SetHandler(TMethod h);
{
StoredH = h;
}
typedef void (*TDataHandler)(void* Self, void* Data);
void DoSomething();
{
((TDataHandler)(StoredH.Code))(StoredH.Data, SomeData);
}
Warning, this is pseudo code, you should adapt it so that it can compile.
