Hi Katolaz,

Here you are an example of two arguments (x,y) passed by reference:

# include <stdio.h>

int main(void)
{

int i=1;
int j=2;

printf( "i = %d j = %d \n", i,j);

func(&i, &j);

printf( "i = %d j = %d \n", i,j);

return 0;

}

void func(int *x, int *y)
{
int k = *x;
*x = *y;
*y = k;
}

This is the output:

i = 1 j = 2
i = 2 j = 1

Passing by value and passing by reference in ANSI C99 are documented in
the following book:

C - The Complete Reference (by Herbert Schildt)
