watch_input_devices()

status_t watch_input_devices	(	BMessenger	target,
		bool	start
	)

Start/stop watching input devices for state changes.

Informs the Input Server that target would like to start/stop receiving B_INPUT_DEVICES_CHANGED messages, reflecting the state of input devices the Input Server is aware of.

The B_INPUT_DEVICES_CHANGED message contains:

• be:opcode An input_device_notifcation constant that identifies which event occured.
• be:device_name A string containing the device's name.
• be:device_type An input_device_type constant representing the device's type.

Parameters

target	Where the device state change messages should or should not be sent.
start	Whether target should start/stop receiving device state change messages.

Returns

A status code.

Return values

B_OK	Watching has successfully been started or stopped.
B_BAD_VALUE	target never started watching for device state changes, though a request was made to stop watching for changes.
Other	errors depending on the state of the Input Server.
