签名后的C ++参数声明[重复](C++ arguments declaration after the signature [duplicate])

 
 
 这个问题在这里已有答案： 
 
 
 
  
 C函数语法，参数列表 6 后面声明的参数类型 
 
 
 
 
 我知道在C / C ++中你声明了这样的函数参数： 
 
type functionName(type arg1,type arg2 )
{
    ...code...
}
 
 但是有一些地方，例如http://www.enderunix.org/docs/eng/daemon.php我在哪里看到一个函数也可以像这样声明 
 
type functionName(arg1, arg2)
type arg1;
type arg2;
{
    ...code..
}
 
 这是一个有效的声明吗？ 我从来没有在任何C / C ++手册中看到过类似的东西，任何人都可以告诉我这是否正确，如果这种声明有效，有什么利弊，如果可能的话，请指点我的手册或文件这解释了这个。 谢谢

 C function syntax, parameter types declared after parameter list  7 answers  
 
 
 
 
I know that in C/C++ you declare function arguments like this:
 
type functionName(type arg1,type arg2 )
{
    ...code...
}
 
However there are a few places, for example here http://www.enderunix.org/docs/eng/daemon.php Where I see that a function can also be declared like this
 
type functionName(arg1, arg2)
type arg1;
type arg2;
{
    ...code..
}
 
Is that a valid declaration? I've never seen anything like that in any C/C++ manual, can anyone tell me if this is correct, what are the pros and cons for this type of declaration if it is valid, and if possible point me to some manual or document that explains this. Thanks
