clang_getCursorDefinition

\brief For a cursor that is either a reference to or a declaration of some entity, retrieve a cursor that describes the definition of that entity.

Some entities can be declared multiple times within a translation unit, but only one of those declarations can also be a definition. For example, given:

\code int f(int, int); int g(int x, int y) { return f(x, y); } int f(int a, int b) { return a + b; } int f(int, int); \endcode

there are three declarations of the function "f", but only the second one is a definition. The clang_getCursorDefinition() function will take any cursor pointing to a declaration of "f" (the first or fourth lines of the example) or a cursor referenced that uses "f" (the call to "f' inside "g") and will return a declaration cursor pointing to the definition (the second "f" declaration).

If given a cursor for which there is no corresponding definition, e.g., because there is no definition of that entity within this translation unit, returns a NULL cursor.
