+Return the indicated Tooltalk message attribute. Attributes are

+suffix of the Tooltalk tt_message_<attribute> function that extracts the value.
+String attribute values are copied, enumerated type values (except disposition)
+are converted to symbols - e.g. TT_HANDLER is 'TT_HANDLER, uid and gid are
+represented by fixnums (small integers), opnum is converted to a string,
+and disposition is converted to a fixnum. We convert opnum (a C int) to a
+string, e.g. 123 => "123" because there's no guarantee that opnums will fit
+within the range of Lisp integers.
+
+Use the 'plist attribute instead of the C API 'user attribute
+for user defined message data. To retrieve the value of a message property
+specify the indicator for argn. For example to get the value of a property
+called 'rflag, use
+ (get-tooltalk-message-attribute message 'plist 'rflag)
+
+To get the value of a message argument use one of the 'arg_val (strings),
+'arg_ival (integers), or 'arg_bval (strings with embedded nulls), attributes.
+For example to get the integer value of the third argument:
+
+ (get-tooltalk-message-attribute message 'arg_ival 2)
+
+As you can see, argument numbers are zero based. The type of each argument
+can be retrieved with the 'arg_type attribute; however, Tooltalk doesn't
+define any semantics for the string value of 'arg_type. Conventionally
+"string" is used for strings and "int" for 32 bit integers. Note that
+Emacs Lisp stores the lengths of strings explicitly (unlike C) so treating the
+value returned by 'arg_bval like a string is fine.
