Are function pointers supported in INNO Setup? I can't find anything in the documentation. I know Delphi/Pascal supports them and as the INNO scripting engine is based on it, I'm hoping it is supported.
A:
I really doubt it, because Inno implements a subset of Pascal in its script language.
What is the task?
I'd like to implement a plugin framework and would like to register plugins and the backend system to then call the functions passed. Example: RegisterPlugin('Pluginname', @InitPlugin, @InvokePlugin);There are other ways of doing it of course...so not critical.

I think, it's better not to rely on Inno's implementation of Pascal script in this case. You better off with something you have better control over.

A:
I just did a little test and function pointers do work indeed. The following [Code] section compiles and works just fine:
type
TStrProc = procedure (const AStr: String);
procedure Call(const AProc: TStrProc; const AStr: String);
begin
AProc(AStr);
end;
procedure ShowStr(const AStr: String);
begin
MsgBox(AStr, mbInformation, MB_OK);
end;
function InitializeSetup(): Boolean;
begin
Call(@ShowStr, 'Hello World!');
end;
BTW: Inno uses the PascalScript engine from RemObjects (http://www.remobjects.com/ps.aspx). Maybe you can find some more information there.
