va_start, va_arg, and va_end macros

[amac]

I was wondering if someone that has used these and gotten them to work would help me out...

I found an example which works... but when I try to do it... it doesnt... I almost type exactly the same thing in the example and still nothing...

#include <stdio.h>
#include <stdarg.h>

int count ( int first, ... );

void main (void)
{
    printf ("%d", count ( 1, 2, 3, 4, 5, 6 ) );
}

int count ( int first, ... )
{

    int count = 1, i = 0;
    va_list start;

    va_start ( start, first );

    while (1)
    {

         i = va_arg (start, int);
         
         if (i != -1) count++;
         else break;

    }

    va_end ( start );

    return count;

}

This is how the example does it... by lookin at it... this should work... but doesnt.

Can anyone help?
