I want to create variable length parameters function in c language like printf()

[rameshbabupeddapalli]

Hi,

I want to create my own variable length parameters function it should work like printf() function.

When i write the program as given below it's working fine
[code=c]
#include<stdio. h>
void main()
{
void fun(int, ...);
fun(1,2);
}

void fun(int a,int b)
{
printf("%d%d",a ,b);
}

but if i write the progran as given below it's not working it's giving error.
#include<stdio. h>
void main()
{
void fun(int, ...);
fun(1,2);
fun(1,2,3);
}

void fun(int a,int b)
{
printf("%d%d",a ,b);
}

void fun(int a,int b,int c)
{
printf("%d%d%d" ,a,b,c);
}
[/code]
The error message is :
error C2084: function 'void __cdecl fun(int ,... )' already has a body

My Questions is Why it's giving error?
We can write many printf functions with different argument lists in a single block, How printf() is working and why my fun() is not working?
please answer to my questions
