Detailed Description

This group contains four general facilities:

• A templatized stored callback mechanism, Callback.
• An event loop interface, DispatchInterface, plus interfaces for receiving socket and timeout notifications.
• A string formatting class, StringBuffer. Provides a printf() style interface for constructing strings, with dynamic allocation.
• An error reporting class, ErrorInfo. This class is used to pass integer code values and string description values of an error condition through multiple layers of method calls.
