Is this procedure a member of a class?  If so, remember that it also sends
SELF although it would be hidden.

I am trying to figure out the correct way to send this procedure to the
lazqtlib. I am getting a crash inside of the C++ library trying to call back
the pascal routine. If this is the case and it is a address and not a
pointer to an address then I know what is going on. The library is looking
for a pointer to an address..

  EventHook(char *WidgetID, void *procpointer) I then have to cast this in
the library
back to an address and attach it to the appropriate object in the internal
widget stack. I get either a access violation or illegal instruction.

That would be the ADDRESS of the procedure.

Not sure why you would grab the address that way though.  What you should do
it set up a type

TSomeType = procedure (myint : integer); cdecl;

then in your class or var area, define a variable of type TSomeType and
assign it to myproc.
You may be doing it that way for a reason I don't understand though....

Hi gents!


A little pascal question for you all..

If I declare a procedure like this.

procedure myproc(myint: integer);cdecl;
begin
end;


I then reference it like this  @myproc what does this really stand for. It
is my assumption that it is a untyped pointer to the address of myproc.  Is
this assumption
correct?
