C6508
warning C6508: invalid annotation: write access is not allowed on const values
Note
This warning occurs only in code that is using a deprecated version of the source-code annotation language (SAL). We recommend that you port your code to use the latest version of SAL. For more information, see Using SAL Annotations to Reduce C/C++ Code Defects.
This warning indicates that the Access property specified on a const parameter implies that it can be written to. For constant values, Access=Read is the only valid setting.
Example
The following code generates this warning:
// C
#include <CodeAnalysis\SourceAnnotations.h>
void fD ([SA_Pre(Deref=1,Access=SA_Write)]const char *pc);
// C++
#include <CodeAnalysis\SourceAnnotations.h>
using namespace vc_attributes;
void f ([Pre(Deref=1,Access=Write)]const char *pc);
To correct this warning, use the following code:
// C
#include <CodeAnalysis\SourceAnnotations.h>
void f ([SA_Pre(Deref=1,Access=SA_Read)]const char *pc);
// C++
#include <CodeAnalysis\SourceAnnotations.h>
using namespace vc_attributes;
void f ([Pre(Deref=1,Access=Read)]const char *pc);
