Hi,

Would it be sufficient to put function genbet(x,y:shortreal):shortreal;C; in the calling program?

Yes.

Is it necessary to have the wrapper unit?

No.

If yes, why is a wrapper needed?

Why units are needed at all ? Why .h file are used in C programming ? To have ONE definition of function, of course. So you do not need to change 10'000 files when genbet definition will be changed...

Thanks.

Actually, I would like to use a fonction named "genbet" in the randlib.c. For that, I have made a little program beta.pas:

 unit beta;
 interface
 {$L /usr/local/include/randlib.h}
 function genbet(x,y:shortreal):shortreal;C;
 implementation
 end.

and test.pas:

 uses
     beta;
 begin
     writeln(genbet(100,150));
 end.
