I really don't know what is the problem
with my email program ...=20
Sory for all that "=3D20 ... ".

Also, the message I send have some line
deleted.=20
I write here again :

-------------------------------------------------
I ALSO FOUND MYSELF A SOLUTION TO MY=20
PROBLEM :

EXAMPLE :
// C function in dll remain the same :
void MyFunction(float ParameterA);

-- but in euphoria I define the function like this :
constant xMyFunction =3D define_c_proc(mydll, "MyFunction", {C_INT})

-- then in the procedure I did the magic thing :
procedure MyFunction(atom ParameterA)

ParameterA =3D bytes_to_int(atom_to_float32(ParameterA))

c_proc(xMyFunction, ParameterA)

end procedure

Please tell me what you think about this ...
I did some tests and it work. The problem is that is slow.

Sorry again.
