RWByteAddressBuffer.Load2

Description

Load two 32-bit unsigned integers from the buffer at the specified location with additional alignment.

Signature

/// Requires Capability Set 1:
vector<uint, 2> RWByteAddressBuffer.Load2(int location);

/// Requires Capability Set 1:
vector<uint, 2> RWByteAddressBuffer.Load2(
    int location,
    int alignment);

/// Requires Capability Set 2:
vector<uint, 2> RWByteAddressBuffer.Load2(
    int location,
    out uint status);

Parameters

location : int

The input address in bytes.

alignment : int

Specifies the alignment of the location, which must be a multiple of 4.

status : uint

[out] The status of the operation.

Return value

Two 32-bit unsigned integers loaded from the buffer.

Remarks

This function only supports when targeting HLSL. You can’t access the output parameter status directly; instead, pass the status to the CheckAccessFullyMapped intrinsic function. CheckAccessFullyMapped returns TRUE if all values from the corresponding Sample, Gather, or Load operation accessed mapped tiles in a tiled resource. If any values were taken from an unmapped tile, CheckAccessFullyMapped returns FALSE. When targeting non-HLSL, the status is always 0.
