4 Async helpers for blocking functions
5
6 Copyright (C) Volker Lendecke 2005
7 Copyright (C) Gerald Carter 2006
8
9 The helpers always consist of three functions:
10
11 * A request setup function that takes the necessary parameters together
12 with a continuation function that is to be called upon completion
13
14 * A private continuation function that is internal only. This is to be
15 called by the lower-level functions in do_async(). Its only task is to
16 properly call the continuation function named above.
17
18 * A worker function that is called inside the appropriate child process.
