Function Documentation

client_gl_memobj_swapchain_create()

struct xrt_swapchain * client_gl_memobj_swapchain_create	(	struct xrt_compositor *	xc,
		const struct xrt_swapchain_create_info *	info,
		struct xrt_swapchain_native *	xscn,
		struct client_gl_swapchain **	out_cglsc
	)

Create a swapchain, belonging to a client_gl_compositor, that uses GL_memory_object and related extensions to use the native buffer.

This is most commonly used on desktop OpenGL.

The caller must ensure that the app context is current.
