Parameters

   o  robot_name - The name of the robot device to be opened. On
      Digital UNIX, if the leading character of the name is not a
      slash (/), /dev/ will be prepended to the name.

   o  volume_tag- A NULL terminated character string that is the
      volume tag to search for.

   o  element_type - The type of robot element on which the
      operation takes place. If an element type of zero (0) is used,
      all elements will be searched starting at element 0 of each
      type and searching all the elements of that type on the robot.
      The order of this search is Slot, Drive, Transport and finally
      Ports.

   o  element_start- A NULL terminated character string that is the
      zero relative address of the element where the search should
      be started. This argument is not used when the element_type is
      zero (0).

   o  element_count - A volume tag search in a large library
      can take a long time. Some applications (a graphic user
      interface for example) may want to break up a large search
      into smaller, quicker sub-searches. When a specific element_
      type is specified only a range specified by the element_name
      and element_count will be searched. This argument is ignored
      when the element_type is zero (0).

   o  result_param- If an element matching the volume_tag string is
      found, the element_info_t will copied into the space pointed
      to by result.

   o  result_name- The zero relative element address of the matching
      element will be copied into the space pointed to by result_
      name. This space should be a character array of size MRD_NAME_
      SIZE.

   o  result_type- The element type of the matching element will be
      copied into the space pointed to by result_type.

   o  log_info - This is a character array that should be at least
      MRD_MAX_LOG_STRING in length. If this function fails as the
      result of a SCSI error, this will be filled with the formatted
      request sense data. If this function fails as the result
      of an operating system error, the operating system message
      particular to the error will be copied into the array.
