(** Message serialization/deserialization *)
exception Data_error of string
(** Exception raised a message can not be sent. The parameter is an
error message.
Possible reasons are: the message is too big or contains too big
arrays. *)
exception Protocol_error of string
(** Exception raised when a received message is not valid.
Possible reasons are:
- a size limit is exceeded
- a name/string/object-path is not valid
- a boolean value is other than 0 or 1
- ... *)

fails if the message contains file descriptors. *)

contains. *)

(** [close_reader reader] closes the given reader.
Note: this does not close the underlying file descriptor. *)

(** [close_writer writer] closes the given writer.
Note: this does not close the underlying file descriptor. *)
