Would it be possible in FPC to pass a type of a variable as a
parameter to
a function?
e.g.
MyFunction(integer);
I have legacy C code that does this via a macro. Hopefully, it can be
done
so I do not need to change the existing code too badly.
This is not possible as such.
What you can do is use generics
MyFunction<integer>
or use typeinfo:
MyFunction(TypeInfo(Integer));
Which of the 2 you need to use depends on the code of course.
Or variants. Or in an emergency: start using/creating an external
preprocessor.
