* @endcode
- * @details
- * TDM stands for Tizen Display Manager. It's the display HAL layer for tizen
- * display server. It offers the frontend APIs(@ref tdm.h) for a frontend user
- * and the abstraction interface(@ref tdm_backend.h) for a hardware vendor.\n
- * \n
- * TDM consists of display/output/layer/pp/capture objects. A frontend user can
- * get the output/layer/pp/capture hardware information with each object.
- * Basically, TDM supposes that all hardware devices have fixed outputs and
- * layers. A frontend user can get these outputs and layers with
- * #tdm_display_get_output_count, #tdm_display_get_output, #tdm_output_get_layer_count
- * and #tdm_output_get_layer. To get a pp/capture object, however, a frontend
- * user need to create a object with #tdm_display_create_pp, #tdm_output_create_capture
- * and #tdm_layer_create_capture if available.\n
- * \n
- * All changes of output/layer/pp/capture objects are applied when commiting.
- * See #tdm_output_commit, #tdm_pp_commit and #tdm_capture_commit.\n
- * \n
- * TDM has its own buffer release mechanism to let an user know when a TDM buffer
- * becomes available for a next job. A frontend user can add a user release handler
- * to a TDM buffer with #tdm_buffer_add_release_handler, and this handler will be
- * called when it's disappered from screen or when pp/capture operation is done.
