Warning C33022

Potentially incorrect HRESULT usage detected (low confidence)

Remarks

This warning is a low-confidence indicator for a function that returns HRESULT, that there's a FALSE that is either eventually returned, or it's assigned to a variable that is returned.

Code analysis name: HRESULT_USAGE_LOW_CONFIDENCE

Example

The following sample code causes warning C33022:

#include <Windows.h>

#define CHECK_RESULT(X) X ? S_OK : FALSE;
#define RETURN_RESULT(X) return CHECK_RESULT(X)

HRESULT foo()
{
    // ......
    RETURN_RESULT(FALSE);   // C33022
}

These warnings are corrected by using proper HRESULT value:

#include <Windows.h>

#define CHECK_RESULT(X) X ? S_OK : E_FAIL;
#define RETURN_RESULT(X) return CHECK_RESULT(X)

HRESULT foo()
{
    // ......
    RETURN_RESULT(FALSE);    // OK
}
