/**
 * PopplerMediaSaveFunc:
 * @buf: (array length=count) (element-type guint8): buffer containing
 *   bytes to be written.
 * @count: number of bytes in @buf.
 * @data: (closure): user data passed to poppler_media_save_to_callback()
 * @error: GError to set on error, or %NULL
 *
 * Specifies the type of the function passed to
 * poppler_media_save_to_callback().  It is called once for each block of
 * bytes that is "written" by poppler_media_save_to_callback().  If
 * successful it should return %TRUE.  If an error occurs it should set
 * @error and return %FALSE, in which case poppler_media_save_to_callback()
 * will fail with the same error.
 *
 * Returns: %TRUE if successful, %FALSE (with @error set) if failed.
 *
 * Since: 0.14
