Adding to a wait queue

I was wondering how I add a task_struct to a Wait Queue in a linux kernel module? For example if I want to add a task_struct called task to a WaitQueue, what function could I use to achive this?

I understand how to add the current module to a wait queue but I want to add other running processes to a queue, for example if vi was running, I need to add that to a wait queue.

You can make the current task block on an waitqueue with wait_event*() functions. See this tutorial, section '6.2.2. Simple Sleeping'.
