Assignment makes pointer from integer without a cast

[Lord Byron]

I am using a function like this:

(...)

short int analyze(long int *id)
{
   long int tid;
   tid = 2001;
   id = tid;
}

The gcc compiler gives a warning: "assignment makes
pointer from integer without a cast", but if I do
this:
   *id = tid;
when it's running, it causes a Bus Error

What do I have to do?!
