#### Declaration [src]

    void
    write_mime_type_async (
      GdkContentProvider* provider,

      int io_priority,
      GCancellable* cancellable,
      GAsyncReadyCallback callback,
      gpointer user_data
    )

#### Description [src]

Asynchronously writes the contents of `provider` to `stream` in the given `mime_type`.
