Why do I get : error C267: 'DrawString': requires ANSI-style prototype?

Friends,

Why do I get : error C267: 'DrawString': requires ANSI-style prototype?

The code :

#define uchar unsigned char 

void DrawString(uint x, uint y, uchar *pStr, uint LineColor,uint FillColor, uchar Mod)

{

    while(1)
    {
        if (*pStr == 0)
        {
            return;
        }

        if (*pStr > 0x80)          
        {
            DrawSingleHz(x, y, pStr, LineColor, FillColor, Mod);
            x += HZ_column;
            pStr += 2;              
        }
        else                        
        {
            DrawSingleAscii(x, y, pStr, LineColor, FillColor, Mod);
            x += 8;
            pStr += 1;              
        }
    }   
}
//=================================

I call it with :

	DrawString(68, 0, "0", RED, YELLOW, NORMAL);

And got error :
error C267: 'DrawString': requires ANSI-style prototype

I think, I put all the input parameters correctly, but why is it happened ?

Thanks for helping

Not seen this type of error before, but first thing to check is are you declaring the function (i.e. either by using a function prototype, or
by having that function appear earlier in the file than the function that calls it)
before you are using it? If not, then you need to declare the function (i.e. have a function prototype) at the beginning of your file.
Also, what kind of compiler is it? is it a C++ compiler?
Maybe the compiler can't resolve the function call to the function declaration if the parameters look to be of the wrong type
(i.e. function overloading).
For instance, (just as an example) is 'NORMAL' definitely of type uchar?
