NULL pointer in CLearn: What is the NULL pointer in C language? When NULL pointer requires and what is the value of a NULL Macro? As we have discussed in chapter "Pointers Declarations in C programming language" that a pointer variable stores the address of another variable. But sometimes ...

How Null Pointer Exception occurs? For the sake of explanation, a null pointer exception has been explained with the help of Java code and C# code; two of the most widely object-oriented languages. A null pointer exception also occurs in C and C++ where actual pointers are used to point ...
A pointer in IDL can exist in either of two states: valid or invalid. • Pointers that point to an IDL variable, or to an undefined variable, are known as valid pointers. Valid pointers may be dereferenced, meaning the variable pointed to may be accessed regardless of whether the variable...

I have made a minimal example of the problem I'm having. When I call JS_EvalFunction the first module is built, and then it iterates to build the array of dependent modules (I think). It iterates through req_module_entries, and req_modul...
In computer programming, null is both a value and a pointer. Null is a built-in constant that has a value of zero. It is the same as the character 0 used to terminate strings in C. Null can also be the value of apointer, which is the same as zero unless theCPUsupports a special...
