C ++ extern函数错误:函数参数过多 [英] C++ extern function error: too many arguments to function

问题描述

我有一个cw.h文件，其中有一堆extern函数，我想从我的cw.cpp文件中调用.

I have a cw.h file with a bunch of extern functions in it that I want to call from my cw.cpp file.

它们在.h中这样表达.文件以及Type结构的声明(只是示例函数，而不是函数的实际名称):

They are expressed like this in the .h. file along with the declarations of the Type struct (just example functions, not the actual names of the functions):

extern Type* new_type(), match(), sharetype();

但是它们的定义和实现在cw.cpp文件中.
每个函数都有一个或多个传递给它的参数.

But their definitions and implementations are in the cw.cpp file.
Each of the functions has 1 or more parameters passed into it.

当我尝试编译时，我不断收到每个函数的错误消息:

When I try compiling, I keep getting this error message for each of the functions:

cw.h:11: error: too many arguments to function Type new_type()
cw.cpp:575: error: at this point in file

我不知道如何解决它.我一直在搜索过去一个小时(-_-)

I have no idea how to fix it. And I've been searching for the past hour (-_-)

编辑[已解决]:

我更改了.h文件中的代码，以匹配在调用函数时传递给函数的参数类型. 没有更多错误.

I changed my code in the .h file to match the types of the parameters being passed into the functions when they're being called. No more errors.

推荐答案

在C ++中，用()声明的函数是原型，意味着该函数不带任何参数.在C ++中，等效于使用(void).它的含义与C语言中的含义不同(即该函数使用了未指定数量的参数).

In C++, a function declared with () is a prototype and means that the function takes no arguments. In C++ it is equivalent to using (void). It doesn't have the same meaning as in C (i.e. that the function takes an unspecified number of arguments).
