奇怪的SAL标注警示 [英] Strange SAL annotation warning
问题描述
我想用Micosoft的SAL标注为我的项目,但我得到以下警告,我不知道为什么。
I'm trying to use Micosoft's SAL annotation for my project, however I get the following warning, and I don't know why.
作为一个例子,我创建了一个新的C ++控制台应用程序,并拥有这code:
As an example, I created a new C++ console application, and have this code:
#include <sal.h>
class Whatever
{
public:
_Check_return_ int Method(__in int number) ;
};
int main()
{
return 0;
}
当我编译使用Visual Studio 2008,我得到以下警告:
When I compile using Visual Studio 2008, I get the following warning:
警告C6540:此功能的使用属性注释,将会使所有现有__declspec注释
warning C6540: The use of attribute annotations on this function will invalidate all of its existing __declspec annotations
在文件c1xxast
我是什么做错了吗?如果我删除无论是 _Check_return _
或 __在
,警告消失。
What am I doing wrong? If I remove either the _Check_return_
or the __in
, the warning goes away.
我找不到警告C6550任何引用。然而,相同的文本可以在这里找到: http://msdn.microsoft.com/ EN-US /库/ dd445322.aspx ,但它不是非常有帮助。
I cannot find any reference to the warning C6550. However the same text can be found here: http://msdn.microsoft.com/en-us/library/dd445322.aspx, but it's not very helpful.
推荐答案
这个问题可能是因为你是混合SAL注释类型。虽然说得很清楚MSDN上,有两种类型的SAL注释:属性和......呃......不会
The problem may be because you are mixing SAL annotation types. Although made very clear on MSDN, there are two types of SAL annotation: attribute and ... er ... not.
的的#define
S IN &LT; sal.h&GT;
VC2005使用非属性的版本,并开始下划线后跟一个小写信。较新版本的VC2008扩展到编译器的属性,并开始(和结束)以下划线后跟一个资本信。
The #define
s in <sal.h>
VC2005 use the non-attribute versions and start with an underscore followed by a lowercase letter. The newer VC2008 versions expand to compiler attributes and start (and end) with an underscore followed by a capital letter.
您已经混合两种类型:
属性:
- _ _在
- _Check_return _
非属性:
- __中
- __ checkReturn
试着改变你的注释坚持使用单一类型的。
Try changing your annotations to use a single type consistently.
