    It's a member access operator for pointer variables.

    Access member of a struct via a pointer.

    So if p is a pointer to an instance of some struct type, and m is a member of that struct type, then p->m accesses the member m of the structure pointed to by p. It is syntactically equivalent to (*p).m
    Right 98% of the time, and don't care about the other 3%.

    If I seem grumpy or unhelpful in reply to you, or tell you you need to demonstrate more effort before you can expect help, it is likely you deserve it. Suck it up, Buttercup, and read this, this, and this before posting again.

    Read about this operator, and the rest of them, here:
