public class DmabufFormats

The `GdkDmabufFormats` struct provides information about supported DMA buffer formats.

You can query whether a given format is supported with [method@Gdk.DmabufFormats.contains] and you can iterate over the list of all supported formats with [method@Gdk.DmabufFormats.get_n_formats] and [method@Gdk.DmabufFormats.get_format].

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 [class@Gdk.DmabufTextureBuilder] for more information about DMA buffers.

Note that DMA buffers only exist on Linux.

Methods:

public unowned DmabufFormats @ref ()
Increases the reference count of this.
public bool contains (uint32 fourcc, uint64 modifier)
Returns whether a given format is contained in this.
public bool equal (DmabufFormats? formats2)
Returns whether this and formats2 contain the same dmabuf formats, in the same order.
public void get_format (size_t idx, out uint32 fourcc, out uint64 modifier)
Gets the fourcc code and modifier for a format that is contained in this.
public size_t get_n_formats ()
Returns the number of formats that the this object contains.
public void unref ()
Decreases the reference count of this.
