XMVectorSetWPtr

Sets the w component of an XMVECTOR containing floating-point data, with a value contained in an instance of float referred to by a pointer.

Syntax

XMVECTOR XMVectorSetWPtr(
         XMVECTOR V,
         const float *w
)  

Parameters

V
Type: XMVECTOR 

[in]

A valid 4D vector storing floating-point data.

w
Type: float *

[in]

Pointer to a float containing the value to be stored in the w element of the XMVECTOR Data Type object V.

Return value

Type: XMVECTOR 

An instance of XMVECTOR Data Type whose w component has been set to the floating-point value provided by the argument w to XMVectorSetWPtr. All other components of the returned XMVECTOR Data Type instance have the same value as those of the input vector V.
