31 * @brief This file contains API related to all operations with media folder in DB. \n
32 * These functions include getting the number of folders and media files filtered from DB, \n
33 * iterating through media files and folders filtered in the given folder from DB; \n
34 * cloning and destroying the media folder, getting its name, ID, absolute path and date \n
35 * and updating the media folder to the media database.

45 * @brief Gets the count of folder for the passed @a filter from the media database.
48 * @param[in] filter The handle to filter \n
49 * To allow searching over different content types, you should use #filter_h.

70 * The @a callback function will be invoked for every retrieved
71 * folder. If @c NULL is passed to the @a filter, no filtering is applied.
75 * @remarks Do not call updating DB fuction like media_folder_update_to_db() in your callback function, your callback function is invoked as inline function.\n
