Detailed Description

Owner of a GBM device together with the render-node descriptor it was created from.

gbm_device_destroy() does not close the descriptor passed to gbm_create_device(), so the descriptor has to be tracked and closed here once the device is gone.

Member Function Documentation

◆ fd()

int wl::gbm_device_t::fd ( ) const

inline

Returns: The render-node descriptor, or -1.

◆ get()

gbm_device * wl::gbm_device_t::get ( ) const

inline

Returns: The GBM device, or nullptr.

◆ init()

bool wl::gbm_device_t::init	(	const std::string &	render_path,
		const gbm_device_accessors_t &	accessors )

Open the render node and create the GBM device on it.

Parameters

render_path	Path of the DRM render node.
accessors	Functions used to open the node and create the device.

Returns: true when the device is ready, false when nothing is held.

◆ operator bool()

wl::gbm_device_t::operator bool ( ) const

inlineexplicit

Returns: true when a GBM device is held.
