Detailed Description

API used to query for a controller's capabilities.

The following API is used to query for the support of individual or groups of capabilities by a particular device.

Function Documentation

cont_has_capabilities()

int cont_has_capabilities	(	const struct maple_device *	cont,
		uint32_t	capabilities
	)

Check for controller capabilities.

Checks whether or not a controller implements the capabilities associated with the given type.

Note

Controller capability reporting is an extremely generic mechanism, such that many peripherals may implement the same capability in completely different ways. For example, the Samba De Amigo maraca controller will advertise itself as a dual-analog device, with each maraca being an analog stick.

Parameters

cont	Pointer to a Maple device structure which implements the CONTROLLER function.
capabilities	Capability mask the controller is expected to implement

Return values

1	The controller supports the given capabilities.
0	The controller doesn't support the given capabilities.
-1	Invalid controller.
