Technical Specification


CallbackProcess is a software development kit for Windows applications, which tracks process and thread creation and termination on-the-fly. Your user-mode application gets notification (callback) when a process- or thread-related operation is performed. Besides simple notifications, CallbackProcess lets your application protect the process or thread from being launched, terminated, suspended or resumed.


CallbackProcess consists of the system-level driver and user-mode API.


The driver intercepts various process- and thread-related requests. If the originator application is in the list of applications, whose requests are filtered, the driver calls the callback/event handler. Your callback can decline or allow the request or handle the request.

User-mode API

User-mode API is simple and introduces about ten functions, specific to driver management operations. Also the API includes several callback functions (events) which your application can handle to get notified about different types of thread or process requests.
The API is used to activate the driver and to set the callbacks.

User-mode APIs are provided for .NET, VCL and C++.
