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.
