Normally, I always check pointers for NULL before using them. However, most of the MFC source code and examples on MSDN® use the returned pointer outright without checking. I'm assuming this is because of the globally created variable theApp. Also, in situations where one needs to make ...
I have one doubt regarding the checking of null for a variable/object. Can anyone let me know the reason for this.

Now a C89 example: void set_elem(int i, void* context) { int* array = (int*)context; array[i] = i; } void example(void) { int array[100]; ct_for(100, set_elem, array, 0); } That last "0" is a null pointer to a canceller - we'll get to that in a moment. Meanwhil...
V740. Exception is of the 'int' type because NULL is defined as 0. Keyword 'nullptr' can be used for 'pointer' type exception. V741. Use of the throw (a, b); pattern. It is possible that type name was omitted: throw MyException(a, b);. V742. Function receives an address of ...
摘要: Our case studies demonstrate that the Checker Framework is scalable, easy to use, and effective in detecting and preventing errors. It has been used to detect real errors in null pointer dereferencing, side effects, equality tests, and initialization, among others....

address range, u can test the address value stored in pointer against the address range and take decision accordingly. > Maybe I am not fully correct with the solution, but It seems right to me at least logically. Please don't use silly abbreviations like "u" for "you". Standard C ha...

This throws the null pointer exception. Hibernate will correctly give me a RoadCond object but there is no values of course in the getters and setters. Obviously I can throw it into a try/catch block but I would think there has to be an easier way to check for a null object. Am I...
