541 Return the indicated Tooltalk message attribute. Attributes are
|
|
542 identified by symbols with the same name (underscores and all) as the
|
|
543 suffix of the Tooltalk tt_message_<attribute> function that extracts the value.
|
|
544 String attribute values are copied, enumerated type values (except disposition)
|
|
545 are converted to symbols - e.g. TT_HANDLER is 'TT_HANDLER, uid and gid are
|
|
546 represented by fixnums (small integers), opnum is converted to a string,
|
|
547 and disposition is converted to a fixnum. We convert opnum (a C int) to a
|
|
548 string, e.g. 123 => "123" because there's no guarantee that opnums will fit
|
|
549 within the range of Lisp integers.
|
|
550
|
|
551 Use the 'plist attribute instead of the C API 'user attribute
|
|
552 for user defined message data. To retrieve the value of a message property
|
|
553 specify the indicator for argn. For example to get the value of a property
|
|
554 called 'rflag, use
|
|
555 (get-tooltalk-message-attribute message 'plist 'rflag)
|
|
556
|
|
557 To get the value of a message argument use one of the 'arg_val (strings),
|
|
558 'arg_ival (integers), or 'arg_bval (strings with embedded nulls), attributes.
|
|
559 For example to get the integer value of the third argument:
|
|
560
|
|
561 (get-tooltalk-message-attribute message 'arg_ival 2)
|
|
562
|
|
563 As you can see, argument numbers are zero based. The type of each argument
|
|
564 can be retrieved with the 'arg_type attribute; however, Tooltalk doesn't
|
|
565 define any semantics for the string value of 'arg_type. Conventionally
|
|
566 "string" is used for strings and "int" for 32 bit integers. Note that
|
|
567 Emacs Lisp stores the lengths of strings explicitly (unlike C) so treating the
|
|
568 value returned by 'arg_bval like a string is fine.
