多空间问题 [英] Polyspace Problem
问题描述
我正在使用polyspace工具。
当我编译以下代码时，我收到错误as
__true_type undefined
struct __true_type {
};
struct __type_traits {
typedef __true_type _h;
};
任何人都可以帮我这个

我认为这是无关紧要的，并且使你的主题成为你的一部分会使人们回应的可能性降低。你的问题只是一个语言问题。
当我编译以下代码时，我收到的错误是
__true_type undefined
这是因为你还没有定义一个叫做__ true_type的类型。

struct __true_type {
};
这里你定义了一个名为__ true_type的结构类型。 （顺便说一句，我/ b $ b）有一种感觉，使用__作为标识符的开头是标准的b $ b。我认为该名称空间是为
实现者）。

这里你试图定义_h （同样，一个领先的_并不是建议使用
，我似乎记得）是一种引用数据类型的方式
" __ true_type"你还没有定义。

};
任何人都可以帮助我这个
我不能完全确定你在这里想要达到的目标，所以它不是很好的b / b
。
我怀疑你需要重新阅读你的参考书，以了解
typedef的用途以及它的用途。
我认为您尝试做的一种方法是： -
typedef struct __true_type true_type_t;
struct __true_type {
};
struct __type_traits {
true_type_t _h;
};

我不完全确定是什么你正试图在这里实现，所以它不是很简单。

typedef和它的用途。

typedef struct __true_type true_type_t;
struct __true_type {
};
struct __type_traits {
true_type_t _h;
};
实际上代码是由我们设计的STL的摘录。我已经修改它以使其变得容易。
但是相同的代码在VC ++编译器中没有任何错误

Hi,
I am using polyspace tool.
When I compile the following code I am getting the error as
__true_type undefined
struct __true_type{
};
struct __type_traits{
typedef __true_type _h;
};
Can anybody help me regarding this

Can anybody help me regarding thisI''m not totally sure what you are trying to achieve here, so it''s not
easy.
I suspect you need to reread your reference books to understand what
typedef does and what it''s for.
One approach to what I think you are trying to do would be :-
typedef struct __true_type true_type_t;
struct __true_type{
};
struct __type_traits{
true_type_t _h;
};

Actually the code is a extract of STL that is designed by us.I have
modified it to make it easy.
But the same code does not give any error in VC++ compiler

"ask in the C++ newsgroup".
