Hotplug handler for the /dev/input/device* devices is registered first, then all currently existing devices are walked and passed to the gp_linux_input_new() function.

This is called by backend drivers that use linux input, e.g. linux drm backend and there is no need to call this function from the application.

Parameters

backend

A backend to registred the handler for

Returns

Returns zero on success non-zero otherwise.

gp_linux_input_new()

int gp_linux_input_new	(	const char *	dev_path,
		gp_backend *	backend
	)

Creates a new linux input driver and attaches it to the backend.

This functions is usually called by the hotplug input driver attached to the backend by the gp_linux_input_hotplug_new() call.

Parameters

dev_path	A path to a linux input device, e.g. /dev/input/event10
backend	A backend to attach the input driver to.

Returns
