how to pass parameters to H file?

[Petr]

I am confused. What is the compiler trying to do?

I try to pass a parameter of type INT or Float and it keeps telling me that the conversion from type INT* to INT and from Float to Float* cannot be performed - what does this mean? Here is a sample code to QB64PE and below that the contents of the H file. It should be fine (but it would have to work) - what did I do wrong?

QB64 code:

Code: (Select All)

Declare Library "plus"
    Function calc_plus% (a As Integer, b As Integer)
End Declare

c% = calc_plus(5, 6)
Print c%

plus.h file code:

Code: (Select All)

int calc_plus (int a, int b)
{
    int c = a + b;
    return c;
}

I'm not big friends with the C language...
