Hi Katolaz,

In this case active_wifis is an argument passed by reference. So:

active_wifis --> is the address
*active_wifis --> is the value

Try doing:

int x = 5;
int *p, *q;

p = &x;     // This is -> p=5
q = p;


printf(" The values are:     %d   %d  ", *p, *q);
printf(" The addresses are:  %d   %d  ",  p,  q);


Aitor.
