What does the "t" mean in dispatch_queue_t?

I can't figure out what “t” means in dispatch_queue_t from the Apple GCD documentation.

At first I thought it was a “stream”, but after reading this question I think it means typedef. If so, what is a dispatch_queue_t typedef?

It stands for "type." If the documents do not indicate why dispatch_queue_t is a typedef for, then this is an opaque type: you should not know because this is an implementation detail (not part of the API specification).
