Debug Message (RTDBG) API Reference
This section includes information about functions and data types of the Debug Message API.
The Debug Message API allows an application to send messages to the Message Viewer without affecting performance. These messages are filtered, so calls will return without performing memory copy or entering the critical section when the console isn't opened.
Video available. See the Debug Message API and Analysis Console video on our YouTube channel for a demo of the Debug Message API.
