Gdk.Dmabuf_Texture

Description

A GdkTexture representing a DMA buffer.

To create a GdkDmabufTexture, use the auxiliary [classGdk.DmabufTextureBuilder] object.

Dma-buf textures can only be created on Linux.

Gasync_Ready_Callback

type Gasync_Ready_Callback is access procedure
  (Source_Object : access Glib.Object.GObject_Record'Class;
   Res           : Glib.G_Async_Result);

Type definition for a function that will be called back when an asynchronous operation within GIO has been completed. Gasync_Ready_Callback callbacks from Gtask.Gtask are guaranteed to be invoked in a later iteration of the thread-default main context (see [methodGlib.MainContext.push_thread_default]) where the Gtask.Gtask was created. All other users of Gasync_Ready_Callback must likewise call it asynchronously in a later iteration of the main context. The asynchronous operation is guaranteed to have held a reference to Source_Object from the time when the *_async function was called, until after this callback returns.

Parameters

Source_Object

the object the asynchronous operation was started with.

Res

a Glib.G_Async_Result.
