02/22/2024

Loads 16-byte aligned data into the x and y components of an XMVECTOR.

Syntax

XMVECTOR XM_CALLCONV XMLoadInt2A(
  [in] const uint32_t *PSource
) noexcept;

Parameters

[in] PSource

Address of the 16-byte aligned data to load.

Return value

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

Remarks

The z and w components of the returned XMVECTOR will be initialized to 0.

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

The following pseudocode shows you 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] = 0;
V.u[3] = 0;

	
return vectorOut;
