I have a C# .NET program P/Invoking into a CUDA DLL. When I use the Visual Profiler to profile the program, an exception is thrown right after the first Console.Clear() line in the C# file and the program is terminated:
Unhandled Exception: System.IO.IOException: The handle is invalid. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.Console.GetBufferInfo(Boolean throwOnNoConsole, Boolean& succeeded) at System.Console.Clear()
This only happens when the program is profiled. Removing the Console.Clear() or adding a try catch block around it no longer causes the program to terminate, but it doesn’t clear the console either.
If I move the console clearing to the CUDA host code using system(“cls”), it still doesn’t clear the console and just outputs a single form feed character (12) when profiled.
