如题。定义一个内置类型比如int型的智能指针可以 shared_ptr<int>这样定义,但不知道如何定义一个指向函数的智能指针。
光阴似箭催人老,日月如移越少年。
#include <stdio.h> #include <memory> typedef void (*Fn)(void); void Foo() { printf("hello world"); } int main() { std::shared_ptr<Fn> ptr(new Fn(Foo)); (*ptr)(); return 0; }
PS: There is function in C++11, so function pointers are generally not used
