Common Desktop Environment: ToolTalk Messaging Overview

Network-Transparent Events

Use the ToolTalk service when your application needs to generate or receive network-transparent events. To be useful, traditional event mechanisms (such as signals and window-system events) require special circumstances; for example, you must know a process or window ID. The ToolTalk service allows events to be expressed naturally: in terms of the file to which the event refers, or the group of processes on the network to which the event is applicable. The ToolTalk service delivers events (called notices) to any interested process anywhere on the network. ToolTalk notices are a flexible and easy way to provide extensibility for your system.
