XMStoreFloat4 function (directxmath.h)
void XM_CALLCONV XMStoreFloat4( [out] XMFLOAT4 *pDestination, [in] FXMVECTOR V ) noexcept;
Address at which to store the data.
Vector containing the data to store.
This function takes a vector and writes the components out to four single-precision floating-point values at the given address. The most significant component is written to the first four bytes of the address, the next most significant component is written to the next four bytes, and so on.
The following pseudocode demonstrates the operation of the function.
pDestination->x = V.x; // 4 bytes to address pDestination pDestination->y = V.y; // 4 bytes to address (uint8_t*)pDestination + 4 pDestination->z = V.z; // 4 bytes to address (uint8_t*)pDestination + 8 pDestination->w = V.w; // 4 bytes to address (uint8_t*)pDestination + 12
