推荐答案

修改?！哇！正确地听自己说，这是没有道理的.如果将函数F从A导入到B，则该代码实际上不存在于B中.您将要修改什么?

现在，从B导出的任何东西的目的总是让F在其他地方被调用，比如说在C中.因此，请考虑1)在C中直接链接A并在C中调用F，2)创建一个"thunk"函数B中的函数F''，链接并在C中调用F''.由于在B中可见F，因为A链接到B，所以F''应该简单地使用具有相同参数的F调用，并透明地将调用返回给调用方F''.

Modify?! Wow! Listen to yourself properly to understand that it makes no sense. If you import a function F from A into B, the code does not physically exist in B. What are you going to modify?

Now, the purpose of having anything exported from B is always having F called somewhere else, let''s say, in C. So, consider 1) linking A in C directly and calling F in C, 2) creating a "thunk" function F'' in B, linking and calling F'' in C. As F is visible in B because A is linked to B, F'' should simply call F with the same very parameters and transparently return the call to the caller of F''.
