Method

GdkDmabufTextureBuilderbuild

since: 4.14

Declaration [src]

GdkTexture*
gdk_dmabuf_texture_builder_build (
  GdkDmabufTextureBuilder* self,
  GDestroyNotify destroy,
  gpointer data,
  GError** error
)

Description [src]

Builds a new GdkTexture with the values set up in the builder.

It is a programming error to call this function if any mandatory property has not been set.

Not all formats defined in the drm_fourcc.h header are supported. You can use gdk_display_get_dmabuf_formats() to get a list of supported formats. If the format is not supported by GTK, NULL will be returned and error will be set.

The destroy function gets called when the returned texture gets released.

It is the responsibility of the caller to keep the file descriptors for the planes open until the created texture is no longer used, and close them afterwards (possibly using the destroy notify).

It is possible to call this function multiple times to create multiple textures, possibly with changing properties in between.

Available since: 4.14

Parameters

destroy

Type: GDestroyNotify

Destroy function to be called when the texture is released.

The argument can be NULL.

data

Type: gpointer

User data to pass to the destroy function.

The argument can be NULL.

The data is owned by the caller of the method.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will be left initialized to NULL by the method if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: GdkTexture

A newly built GdkTexture or NULL if the format is not supported.

The caller of the method takes ownership of the returned data, and is responsible for freeing it.

The return value can be NULL.
