This function returns a pointer to an int , if you write without an asterisk, then it will return just an int .

The difference is that the pointer is not a variable value, but a link to the memory area.

A simple example where a function returns a pointer:

 int *max (int *a, int *b) { if (*a > *b) return a; return b; } int main() { int a, b, *aptr = &a, *bptr = &b; *max(aptr, bptr) += 1; return 0; }
