Function Documentation

app_subsystems_cleanup()

void app_subsystems_cleanup	(	struct App *	app,
		const SubsystemDescriptor *	table
	)

Walk table in reverse, calling cleanup() for each entry.

Skips entries whose cleanup function pointer is NULL. The table must be terminated by a {0} sentinel entry. Intended for the normal shutdown path after a successful init.

app_subsystems_init()

int app_subsystems_init	(	struct App *	app,
		const SubsystemDescriptor *	table
	)

Walk table forward calling init() until the sentinel {0}.

On the first failure at index N, cleanup() is called in reverse for entries [N-1 .. 0], then 0 is returned. The table must be terminated by a {0} sentinel entry.

Returns

1 if all init() calls succeed, 0 on first failure.
