Annotation conflict: 'name' property conflicts with previously specified property
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 the presence of conflicting properties in the annotation. The warning typically occurs when multiple properties that serve similar purpose are used to annotate a parameter or return value. To correct the warning, you must choose the property that best addresses your need.
Code analysis name: CONFLICTING_ATTRIBUTE_PROPERTY_VALUES
The following code generates this warning because both ValidElementsConst and ValidBytesConst provide a mechanism to allow valid data to be read:
// C
#include <CodeAnalysis\SourceAnnotations.h>
void fd([SA_Pre(ValidElementsConst =4, ValidBytesConst =4)] char pch[]);
// C++
#include <CodeAnalysis\SourceAnnotations.h>
using namespace vc_attributes;
void f( [Pre(ValidElementsConst=4, ValidBytesConst=4 )] char pch[] );
To correct this warning, use the most appropriate property, as shown in the following code:
// C
#include <CodeAnalysis\SourceAnnotations.h>
void f( [SA_Pre(ValidElementsConst=4)] char pch[] );
// C++
#include <CodeAnalysis\SourceAnnotations.h>
using namespace vc_attributes;
void f( [Pre(ValidElementsConst=4)] char pch[] );
