60.1 SXEmacs ToolTalk API Summary

The SXEmacs Lisp interface to ToolTalk is similar, at least in spirit, to the standard C ToolTalk API. Only the message and pattern parts of the API are supported at present; more of the API could be added if needed. The Lisp interface departs from the C API in a few ways:

• ToolTalk is initialized automatically at SXEmacs startup-time. Messages can only be sent other ToolTalk applications connected to the same X11 server that SXEmacs is running on.
• There are fewer entry points; polymorphic functions with keyword arguments are used instead.
• The callback interface is simpler and marginally less functional. A single callback may be associated with a message or a pattern; the callback is specified with a Lisp symbol (the symbol should have a function binding).
• The session attribute for messages and patterns is always initialized to the default session.
• Anywhere a ToolTalk enum constant, e.g. ‘TT_SESSION’, is valid, one can substitute the corresponding symbol, e.g. 'TT_SESSION. This simplifies building lists that represent messages and patterns.
