XMComparisonAllFalse function (directxmath.h)

Article
02/22/2024

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

Syntax

bool XMComparisonAllFalse(
  [in] uint32_t CR
) noexcept;

Parameters

[in] CR

Comparison value to test. The comparison value is typically retrieved using a recording version of a 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).

Platform Requirements

Microsoft Visual Studio 2010 or Microsoft Visual Studio 2012 with the Windows SDK for Windows 8. Supported for Win32 desktop apps, Windows Store apps, and Windows Phone 8 apps.
