Hello Thank you for the suggestion, yes, I had used that before. I did just check, it's runtime checks. I had hoped for something at compile time. warning for every function that didn't check pointer for NULL before de-referencing.
You might want to have a look at <http://cppcheck.sourceforge.net/demo/>. There are some 'NULL pointers' examples which answers your exact question.
If you use Debian or Ubuntu, you can install cppcheck with `sudo aptitude install cppcheck`. -- Best regards, Liu Hao
