#HOW TO WRITE C CODE IN VISUAL STUDIO 2017 CODE#

It seems it's never going to meet the standard as far as this matter is concerned, or at least not any time soon. Yet Visual C++ has big problems with that. As specified by the modern C++ standard, this cannot equal NULL.

PVS-Studio analyzer is right in criticizing code that checks the this pointer for NULL.

There were more than 250 warnings like that. You should include the corresponding header rather than declare the type manually.ДЄs you understand, this diagnostic doesn't apply to Visual C++ libraries, for they are just the place to contain the declarations of such types. The analyzer is totally correct in saying so. The system header file should be used: #include. PVS-Studio analyzer issues the following warning for this: V677 Custom declaration of a standard 'DWORD' type. For example: typedef unsigned long DWORD It's bad and dangerous to declare system data types manually. You see, the analyzer issued lots of warnings that were totally correct yet completely false. Besides, there is one peculiar thing about the libraries. Remember, I checked only part of the files, and did it in an unconventional way. However, you can't use these figures to make any interpretations or draw any conclusions!

743 general-analysis (GA) warnings of Medium certainty level.

433 general-analysis (GA) warnings of High certainty level.I'm afraid I can't give you concrete figures on false positives this time. A more thorough and correct check is something that the Visual C++ developers should do themselves, and I'm ready to help them with that. Because of that, PVS-Studio failed to check some of the files, but it doesn't matter much from the viewpoint of my goal, which was to write the article. I just started a new solution and added the files from the libraries to it. Secondly, I didn't try to build the projects in an honest way. Besides, it helps us speed up the analysis process a little, as the analyzer doesn't have to perform full-fledged parsing and analysis of inline functions' bodies. There's no point in generating such warnings by default, as they would only distract people. By copying files into another folder I trick PVS-Studio into generating the warnings I need.Д«y the way, this also explains the absence of feedback from Visual C++ users on warnings in the libraries as mentioned in the tweet quoted above. I confess that I didn't bother to perform proper, full-fledged analysis, as it's a complicated task for me.ДЇirstly, I had to make copies of all the libraries and put them in another folder otherwise, the analyzer wouldn't have been able to produce diagnostic messages for them because it doesn't do that for system libraries. However, the version number doesn't matter that much because it's an article popularizing static analysis in general and PVS-Studio analyzer in particular, rather than a bug report.

The version of the libraries that I had on my computer at the time was dated. What I was checking were the C++ libraries that come with the recently released Visual Studio 2017 version. I did this check using the latest currently available version of PVS-Studio analyzer (6.15). Indeed, I didn't tell the world about the bugs in Visual Studio 2017 libraries! Well then, challenge accepted!ДЄs you can see, it's been a month since the tweet (March 31-st), so I admit I've been dragging my feet over the reply, but now I'm going to mend that.
