Likely incorrect HRESULT usage detected.
Remarks
This warning is a high-confidence indication that an HRESULT-returning function returns FALSE.
Code analysis name: HRESULT_LIKELY_INCORRECT_USAGE
Example
The following sample code causes warning C33020:
#include <Windows.h>
HRESULT foo()
{
// ......
return FALSE; // C33020
}
These warnings are corrected by using the proper HRESULT value:
#include <Windows.h>
HRESULT foo()
{
// ......
return E_FAIL; // OK
}
