I am trying to use the Micosoft SAL annotation for my project, however I get the following warning and I don't know why.
As an example, I created a new C ++ console application and got this code:
#include <sal.h>
class Whatever
{
public:
_Check_return_ int Method(__in int number) ;
};
int main()
{
return 0;
}
When I compile using Visual Studio 2008, I get the following warning:
warning C6540: using attribute annotations for this function will invalidate all existing __declspec annotations
In the file "c1xxast"
What am I doing wrong? If I delete either _Check_return_, or __in, the warning will disappear.
I can not find the link to warning C6550. However, the same text can be found here: http://msdn.microsoft.com/en-us/library/dd445322.aspx , but this is not very useful.
