Regarding linked list (delete function)

Question

Hey can anyone explain me the linked list code.
I am stuck at a line which says
while (q->link->link!=NULL) /*not understood this part*/
{
if(q->link->info==data)
{
q->link=temp->link;.
free (temp);
return;
}
q=q->link;
}

Here q is a pointer pointing to node
temp is a variable
It is a structure struct node
{
int data;
struct node*link;
}
I don't understand the double arrow used please help me clarifying it
