The database is created when my C++ object is created.

The object constructor is:

DbValentinaBase::DbValentinaBase()
{
	// This routine knows not to initialize more than once
     PVInitializeDBSystem();

	DB = FBL::CreateDatabase();
}

// And the initializing routine is:

static long	gPVDBSystemRefCount	= 0;

static unsigned long gPVSizeOfDBCache = 0;
static unsigned long gPVDefaultSizeOfDBCache = 16 * 1024 * 1024;

void PVInitializeDBSystem( unsigned long cacheSize )
{
	unsigned long cacheSizeToUse;
	
	if ( gPVDBSystemRefCount <= 0 )
	{
		if ( cacheSize > 0 )
		{
			cacheSizeToUse = cacheSize;
		} else {
			cacheSizeToUse = gPVDefaultSizeOfDBCache;
		}
		
		// initialize the Valentina kernel: cache size, MacOS serial  
number, Windows serial number
		gPVSizeOfDBCache = ValentinaInit( cacheSize,  
kOurValentinaSerialNumber, NULL );
		printf( "ValentinaInit: gPVSizeOfDBCache = %lu\n",  
gPVSizeOfDBCache );	// DEBUG: REMOVE LATER Prove we initialized
		
		gPVDBSystemRefCount = 1;
	} else {
		++gPVDBSystemRefCount;
	}
}
