Assigning an Existing Routine

New features since Delphi 7 > Anonymous Methods > Assigning an Existing Routine

1 Assigning a Free Procedure / Function

Delphi

p := GlobalProc;

C++ portable

p = &GlobalProc;

C++Builder

p = d2c::bind_free_proc0(&GlobalProc);

Free functions can be assigned directly if their signature matches.

2 Assigning an Instance Method

Delphi

p := Obj.Method;

C++ portable

p = d2c::make_callback(Obj, &TClass::Method);

C++Builder

p = d2c::bind_proc0(Obj, &TClass::Method);

the generated callable internally binds the object pointer and forwards calls to the member function.
