4 Async helpers for blocking functions
6 Copyright (C) Volker Lendecke 2005
7 Copyright (C) Gerald Carter 2006
8 Copyright (C) Simo Sorce 2007
10 The helpers always consist of three functions:
12 * A request setup function that takes the necessary parameters together
13 with a continuation function that is to be called upon completion
15 * A private continuation function that is internal only. This is to be
16 called by the lower-level functions in do_async(). Its only task is to
17 properly call the continuation function named above.
19 * A worker function that is called inside the appropriate child process.
