You can use the debugger engine to write both debugger extension libraries and stand-alone applications. Such applications are referred to as debugger engine applications. A debugger engine application that uses the full functionality of the debugger engine is called a debugger. For example, WinDbg, CDB, NTSD, and KD are debuggers; the debugger engine provides the core of their functionality.
Examining and Manipulating Targets:
This is a preliminary document and is currently incomplete.
For many concepts relating to the debuggers and the debugger engine that are not yet documented here, look in the Debugging Techniques section of this documentation.
To obtain some of the currently undocumented functionality of the debugger engine API, use the Execute method to execute individual debugger commands.
