XMComparisonAllFalse method

Tests the comparison value to determine if all of the compared components are false.

Syntax


bool XMComparisonAllFalse(
  [in]  uint32_t CR
);

Parameters

CR [in]

Comparison value to test. The comparison value is typically retrieved using a recording version of an DirectXMath function such as XMVector4EqualR. The names of the recording functions end with an "R".

Return value

Returns true if all of the compared components are false.

Remarks

The following code snippet highlights how this function might be used:


uint32_t comparisonValue = XMVector4EqualR( V1, V2 );
if( XMComparisonAllFalse( comparisonValue ) )
{
	DoStuff();
}

The DoStuff function will be called only if all four components of V1 and V2 are different (all compared components are false).
