wlr_dmabuf_v1_buffer_from_buffer_resource() 

struct wlr_dmabuf_v1_buffer *wlr_dmabuf_v1_buffer_from_buffer_resource(​struct wl_resource *buffer_resource);

Returns the struct wlr_dmabuf_buffer if the given resource was created via the linux-dmabuf buffer protocol.

wlr_dmabuf_v1_resource_is_buffer() 

bool wlr_dmabuf_v1_resource_is_buffer(​struct wl_resource *buffer_resource);

Returns true if the given resource was created via the linux-dmabuf buffer protocol, false otherwise

wlr_linux_dmabuf_v1_create() 

struct wlr_linux_dmabuf_v1 *wlr_linux_dmabuf_v1_create(​struct wl_display *display, struct wlr_renderer *renderer);

Create linux-dmabuf interface.

wlr_linux_dmabuf_v1_set_surface_feedback() 

bool wlr_linux_dmabuf_v1_set_surface_feedback(​struct wlr_linux_dmabuf_v1 *linux_dmabuf, struct wlr_surface *surface, const struct wlr_linux_dmabuf_feedback_v1 *feedback);

Set a surface's DMA-BUF feedback.

Passing a NULL feedback resets it to the default feedback.
