31 * @brief This file contains the media filter API and related operation with filters. \n
32 * The functions include: creating and destroying media filter handles that are used to get the filtered information, \n
33 * making free all resources related to the filter handle, limiting number of items returned, setting conditions for the filter, \n
34 * setting and getting media filter's content order and ordering keyword either descending or ascending.

43 * @brief Creates a media filter handle.
44 * @details This function creates a media filter handle. The handle can be
45 * used to get the filtered information based on filter properties i.e. offset, count, condition for searching and order.
