* Prototypes for functions in IOManager.c and elsewhere
*
* Hooks for the I/O subsystem(s) that are called from other parts of the RTS.
*
* There are several different I/O subsystem implementations (aka I/O managers),
* for different platforms (notably Windows vs others), and for the threaded vs
* non-threaded RTS. These implementations all need hooks into other parts of
* the RTS, such as startup/shutdown, the scheduler and other special features.
*
* To keep things comprehensible, all the hooks used by all the different I/O
* subsystem implementations are centralised here. Not all implementations use
* all hooks.
