1. module GI.Gdk.Structs.DmabufFormats

   The GdkDmabufFormats struct provides information about supported DMA buffer formats. You can query whether a given format is supported with dmabufFormatsContains and you can iterate over the list of all supported formats with dmabufFormatsGetNFormats and dmabufFormatsGetFormat. The list of supported formats is sorted by preference, with the best formats coming first. The list may contains (format, modifier) pairs where the modifier is DMA_FORMAT_MOD_INVALID, indicating that _implicit modifiers_ may be used with this format. See DmabufTextureBuilder for more information about DMA buffers. Note that DMA buffers only exist on Linux. Since: 4.14

2. newtype DmabufFormats

   gi-gdk4	GI.Gdk.Structs.DmabufFormats

   Memory-managed wrapper type.

3. DmabufFormats :: ManagedPtr DmabufFormats -> DmabufFormats

   gi-gdk4	GI.Gdk.Structs.DmabufFormats

   No documentation available.

4. dmabufFormatsContains :: (HasCallStack, MonadIO m) => DmabufFormats -> Word32 -> Word64 -> m Bool

   gi-gdk4	GI.Gdk.Structs.DmabufFormats

   Returns whether a given format is contained in formats. Since: 4.14

5. dmabufFormatsEqual :: (HasCallStack, MonadIO m) => Maybe DmabufFormats -> Maybe DmabufFormats -> m Bool

   gi-gdk4	GI.Gdk.Structs.DmabufFormats

   Returns whether formats1 and formats2 contain the same dmabuf formats, in the same order. Since: 4.14

6. dmabufFormatsGetFormat :: (HasCallStack, MonadIO m) => DmabufFormats -> CSize -> m (Word32, Word64)

   gi-gdk4	GI.Gdk.Structs.DmabufFormats

   Gets the fourcc code and modifier for a format that is contained in formats. Since: 4.14

7. dmabufFormatsGetNFormats :: (HasCallStack, MonadIO m) => DmabufFormats -> m CSize

   gi-gdk4	GI.Gdk.Structs.DmabufFormats

   Returns the number of formats that the formats object contains. Note that DMA buffers are a Linux concept, so on other platforms, dmabufFormatsGetNFormats will always return zero. Since: 4.14

8. dmabufFormatsRef :: (HasCallStack, MonadIO m) => DmabufFormats -> m DmabufFormats

   gi-gdk4	GI.Gdk.Structs.DmabufFormats

   Increases the reference count of formats. Since: 4.14

9. dmabufFormatsUnref :: (HasCallStack, MonadIO m) => DmabufFormats -> m ()

   gi-gdk4	GI.Gdk.Structs.DmabufFormats

   Decreases the reference count of formats. When the reference count reaches zero, the object is freed. Since: 4.14

10. textureDownloaderGetFormat :: (HasCallStack, MonadIO m) => TextureDownloader -> m MemoryFormat

    gi-gdk4	GI.Gdk.Structs.TextureDownloader

    Gets the format that the data will be downloaded in. Since: 4.10
