XMLoadInt4A method

Loads 16-byte aligned data into an XMVECTOR, without type checking.

Note  This function is provided for backward compatibility with the Xbox Math library. It is recommended that XMLoadInt4A be used when loading integer data and XMLoadFloat4A be used when loading floating point data.

Syntax


XMVECTOR XMLoadInt4A(
  [in]  const VOID *pSource
);

Parameters

pSource [in]

Address of the 16-byte aligned data to load.

Return value

Returns an XMVECTOR loaded with the data from the pSource parameter.

Remarks

To convert the loaded XMVECTOR into float values, use XMConvertVectorUIntToFloat or XMConvertVectorIntToFloat.

The following pseudocode demonstrates the operation of the function.


XMVECTOR vectorOut;

uint32_t* pElement = (uint32_t*)pSource;

assert(((uint32_t_PTR)pSource & 0xF) == 0);

V.u[0] = pElement[0];
V.u[1] = pElement[1];
V.u[2] = pElement[2];
V.u[3] = pElement[3];
	
return vectorOut;
