c++ - 有什么方法可以通过在 C++ 中读取文件来构造函数指针

Question

我在文件中有一个函数原型(prototype)。在 C++ 中，有什么方法可以通过在运行时读取文件来创建函数指针吗？

您正在正确寻找libffi , 来自 Wikipedia :

libffi is a foreign function interface library. It provides a C programming language interface for calling natively compiled functions given information about the target function at run time instead of compile time. It also implements the opposite functionality: libffi can produce a pointer to a function that can accept and decode any combination of arguments defined at run time.
