One convenience function is provided that will start the Thread Validator GUI (if it is not already running), then load the Thread Validator execution tracer into your process and start tracing it.
extern "C"
void loadValidatorIntoApplication();
To use this function #include loadValidatorIntoApplication.h into your code.
The source files can be found in the API directory in the Thread Validator install directory.
Just add these files to your project and build.
