Hello!

According to Fausto Iannuzzi:

I have read it's possible to call gcc functions from a gpc program or unit adding ";C" to functions' declaration. Is it also possible to call or use gpc functions, or generally gpc code, from a gcc program?

Yes: To call the Pascal procedure

Procedure foo ( Var Bar: Integer );

from a C program, use the header

extern void Foo ( int *bar );

Note that the First Character Of The Pascal Procedure Is Capitalized.

Compile the Pascal source as a Unit or Module to avoid a `main()' function to be generated from it.

Does gpc support operator overloading?

Yes:

Type Foo = <whatever>;

Operator + ( x, y: Foo ) = z: Foo;

begin (* Foo + Foo *) <calculate z out of x and y>; end (* Foo + Foo *);

Hope this helps,

Peter
