/** \defgroup CINDEX libclang: C Interface to Clang
*
* The C Interface to Clang provides a relatively small API that exposes
* facilities for parsing source code into an abstract syntax tree (AST),
* loading already-parsed ASTs, traversing the AST, associating
* physical source locations with elements within the AST, and other
* facilities that support Clang-based development tools.
*
* This C interface to Clang will never provide all of the information
* representation stored in Clang's C++ AST, nor should it: the intent is to
* maintain an API that is relatively stable from one release to the next,
* providing only the basic functionality needed to support development tools.
*
* To avoid namespace pollution, data types are prefixed with "CX" and
* functions are prefixed with "clang_".

* \brief Determine the set of methods that are overridden by the given

*
* In both Objective-C and C++, a method (aka virtual member function,
* in C++) can override a virtual method in a base class. For
* Objective-C, a method is said to override any method in the class's
* base class, its protocols, or its categories' protocols, that has the same
* selector and is of the same kind (class or instance).
* If no such method exists, the search continues to the class's superclass,
* its protocols, and its categories, and so on. A method from an Objective-C
* implementation is considered to override the same methods as its
* corresponding method in the interface.
*
* For C++, a virtual member function overrides any virtual member
* function with the same signature that occurs in its base
* classes. With multiple inheritance, a virtual member function can
* override several virtual member functions coming from different
* base classes.
*
* In all cases, this function determines the immediate overridden
* method, rather than all of the overridden methods. For example, if
* a method is originally declared in a class A, then overridden in B
* (which in inherits from A) and also in C (which inherited from B),
* then the only overridden method returned from this function when
* invoked on C's method will be B's method. The client may then
* invoke this function again, given the previously-found overridden
* methods, to map out the complete method-override set.
*
* \param cursor A cursor representing an Objective-C or C++
* method. This routine will compute the set of methods that this
* method overrides.
*
* \param overridden A pointer whose pointee will be replaced with a
* pointer to an array of cursors, representing the set of overridden
* methods. If there are no overridden methods, the pointee will be
* set to NULL. The pointee must be freed via a call to
