warning C6517: Invalid annotation: 'SAL_readableTo' property may not be specified on buffers that are not readable: 'Param\(1)'.

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 SAL_readableTo property does not have the required read access. You cannot use this property to annotate a parameter without providing read access.

Example

The following code generates this warning because read access is not granted on the buffer:

#include <CodeAnalysis\SourceAnnotations.h>  
using namespace vc_attributes;  
void f([Pre( ValidBytesConst=10 )][Pre( Deref=1, Access=Write )] char* buffer );  
  

To correct this warning, grant read access as shown in the following code:

#include <CodeAnalysis\SourceAnnotations.h>  
using namespace vc_attributes;  
void f([Pre( ValidBytesConst=10 )][Pre( Deref=1, Access=Read)] char* buffer );
