How to log output from C to the VS command line?

[kevinburke]

What is the best way to add print statements and get them to display in Visual Studio? For when you don't necessarily want to set a breakpoint, but do want to inspect some values. Let me know and I'll add it to the wiki.

printf() should work

Thanks for replying! So, I tried adding a printf("Hello World\n"); line to the code, and toggling a breakpoint at that line. I successfully got the code to stop executing, then pressed "Continue", then checked the "Output" box in VS for output, and didn't see anything.

Am I looking in the wrong place? Is my printf syntax incorrect? I believe the code is executing because I was able to stop execution exactly on that line.

Yeah, sometimes printf() doesn't work (especially in GUI Apps) :(. There's also another Windows specific function called OutputDebugString() http://stackoverflow.com/questions/3009042/how-to-view-printf-output-in-a-win32-application-on-visual-studio-2010

EDIT: Well it appears we can't use printf because OpenRCT2 is a DLL and not an EXE. http://forums.codeguru.com/showthread.php?399253-Console-Outputting-via-printf-from-DLL

OutputDebugString() works (for me at least..)

Thanks! I updated the wiki.
