 Posted: Tue Sep 19, 2006 9:10 am Post subject: Passing array to methode |
 |
|
Hi everyone,
recently I have trouble to pass an array (unsigned char color[3]) to a
methode by reference and collect the return value by reference.
I wanted something like:
unsigned char[3]& changeColor(unsigned char[3]& color);
How would the correct syntax look like?
Thanks in advance,
Thomas Kowalski |

I suppose that this is a point where you can get around a typedef.
typedef unsigned char CharArray[3];
CharArray& changeColor (CharArray& p_Color)
{
return p_Color;
}

If you pass the array to the function by reference, why
do you wnat to return it as a reference as well ?

I'd use a typedef:
typedef unsigned char Color[3];
Color& changeColor(Color & col)
{
return col;
}
int main()
{
Color c;
Color& b = changeColor(c);
return 0;
}
But I really don't understand what you want to achieve with this.

If you see it, it's quite simple (hit my head). Thanks

Actually I mixed two different methodes. |
I have a getter and and change methode but I combined them to keep the
text short.
Thanks,
