non static number of function parameters?

Ive seen some library functions that do it, but lets say...


How would you write a max() function that could take 2 or more parameters, without rewriting the function for 3 params, 4 params, 5 params, etc..?

Code:

int max (int num_para, ... ) {
// Stuff to do the compares for each item
return the_value_of_the_max_item;
}
