  and reads a message argument.	 The following modes are defined: The
  argument is written by the sender and read by the handler and any
  observers.
  The argument is written by the handler and read by the sender and any reply
  observers.
  The argument is written by the sender and the handler and read by all.

  The vtype argument describes the type of argument data being added.  The
  type ALL matches any argument value type.  The value argument is the value
  to fill in.  This value must be an unsigned character string.	 A NULL
  matches any value.

  status of the operation as one of the following Tt_status values: The
  operation completed successfully.
