So I still have some questions... I have tried with a C routine and the pascal unit and program but it doesn't work.

In short: To use functions

extern double foo (double x);
extern void bar (void);

Where are these functions and in which form? Is it a C program or do I have to put it in the pascal unit or program?

you write a Pascal unit as follows:

unit FooBar;

interface

function Foo (x: Real); C;
procedure Bar; C;

implementation

end.

Same questions for this part. Is it a file named FooBar or FooBar.p or something else?...

Then your program can call the functions:

program Something;

uses
  FooBar;

begin
  Bar;
  writeln (Foo (42))
end.

I guess that if I manage to define correctly the 2 previous parts, it will be ok...

Thanks for help,

Nathalie
