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