VARIANT_BOOL

VARIANT_BOOL is a type currently defined as a short:

/* 0 == FALSE, -1 == TRUE */

typedef short VARIANT_BOOL;

#define VARIANT_TRUE ((VARIANT_BOOL)-1)

#define VARIANT_FALSE ((VARIANT_BOOL)0)

Here is an example

   if (VARIANT_TRUE == pCompOcc->ReferencedDocumentDescriptor->ReferenceMissing) {

       // Maybe a missing and skipped component...

       continue ;

   }

Here is an example:

  VARIANT_BOOL bSuppressed = pFeaturePatternElement->GetSuppressed () ;

  TRACE (L"Element %d suppressed = %d\n",iElem,bSuppressed) ;

In this case bSuppressed will show either -1 (true) or 0 (false).

You can use the predefined macros VARIANT_TRUE and VARIANT_FALSE as values.

Since VARIANT_FALSE is 0 you can use them in ifs like this:

if (p->InventorFunction()) {

    ...do something...

}
