o robot_info - This is the address of a robot_info_t structure initialized using mrd_startup(3mrd) or mrd_show(3mrd). This data structure contains the element starting address and counts for each type of element, which are needed to map an absolute element to the correct zero relative address and type. o address - This is the absolute element address that is to be mapped. o result - This is the address where the zero relative element address is to be written. Like other element addresses used by the Media Robot Driver Library, it is a character string. A character array of MRD_NAME_SIZE bytes should be used.
