指向member function的指针的声明语法,以及指向"member selection运算符"的指针,其作用是作为 this 指针的空间保留者.这这也就是为什么 static member function(没有 this 指针)的类型是"函数指针",而不是"指向member function的指针"的原因. 使用一个"member function指针",假设并不用于 virtual function,多重继承,...

Expressions such as &(C::m) or &m inside C's member function do not form pointers to members. Such a pointer may be used as the right-hand operand of the pointer-to-member access operators operator.* and operator->*: struct C { int m; }; int main() { int C::* p = &C:...
The this pointer is a compiler-generated pointer to the current object in nonstatic member functions.

a function with gsl. Therefor I have to define a function f (the integrant, which has to be of the form double (*)(double, void*)). For the call of the gsl integration method I need to define a struct, which contains a pointer to a function (this struct is called gsl_function)...
