WTTLogCheckResultEx

The WTTLogCheckResultEx function checks a specified result against a target result and logs an error if both the value and type match.

HRESULT WTTLogCheckResultEx (
  LONG  hDevice,           
  DWORD  dwResultToCheck,  
  DWORD  dwResultType,     
  DWORD  dwTargetResult,
  DWORD  dwTargetResultType,
  LPWSTR  pwszFile,         
  ULONG  ulLine,           
  LPWSTR  pwszErrMsg      
);
