# RasterizerOrderedByteAddressBuffer\.Load4Aligned
## Description
Load four 32-bit unsigned integers from the buffer at the specified location with a known alignment.
## Signature
vector<uint, 4> RasterizerOrderedByteAddressBuffer.Load4Aligned(
uint location,
uint alignment);
vector<uint, 4> RasterizerOrderedByteAddressBuffer.Load4Aligned(
uint location);
## Parameters
#### location : uint
The input address in bytes, which must be a multiple of 4.
#### alignment : uint
The known alignment of location, which must be a multiple of 4.
## Return value
Four 32-bit unsigned integers loaded from the buffer.
## Remarks
On HLSL, alignment is informational only; the load is emitted as the native .Load4
intrinsic, which does not accept an alignment operand. On other targets, alignment is
forwarded to the lowered load instruction.
