Unix SMB/CIFS implementation.
Async helpers for blocking functions
Copyright (C) Volker Lendecke 2005
Copyright (C) Gerald Carter 2006
The helpers always consist of three functions:
* A request setup function that takes the necessary parameters together
with a continuation function that is to be called upon completion
* A private continuation function that is internal only. This is to be
called by the lower-level functions in do_async(). Its only task is to
properly call the continuation function named above.
* A worker function that is called inside the appropriate child process.
