这个函数的返回类型是什么?

[英]What is the return type of this function?

I got this line into a macro definition of a class 我把这一行放到了一个类的宏定义中

virtual const char *GetEventName() const
{
    return #classname;
}

What is happening in this function and its return type? 这个函数及其返回类型发生了什么?

If classname is one of the arguements of the macro, #classname is a string version of its value. 如果classname是宏的参数之一,则#classname是其值的字符串版本。 So if classname were SomeType , #classname would be the equivalent of "SomeType" 因此,如果classnameSomeType#classname将等同于"SomeType"

Since it is returning a string (c string) the return type is const char* 因为它返回一个字符串(c字符串),返回类型是const char *
