(middle) fp1 is → (right, nothing) → (left) a pointer to → (right) a function that takes an int → (left) and returns a pointer to → (right) an array of 10 → (left) void pointers. 连起来就是:fp1 is a pointer to a function that takes an int and returns a pointer to ...

指向结构体的指针（Pointers to Structures）在这个例子中，我们定义了一个Point结构体来表示二维平面上的一个点。然后，我们声明一个指向Point结构体的指针ptr，并将其指向结构体变量p。通过指针，我们可以直接访问结构体的成员，并将指针传递给函数以操作结构体。结构体的自引用（Self-referential Structures）这个例子...

is not completely correct and may not find all calls of a function. This is mainly true for calls that are done via function pointers. Calltree is able to detect recursive function calls (e.g. functions that call themselves). Recursive function calls are marked with an ellipsis in the ...
