RWByteAddressBuffer.Load

Description

Load a 32-bit unsigned integer or value with type of T from the buffer at the specified location.

Signature

/// Requires Capability Set 1:
uint RWByteAddressBuffer.Load(int location);

/// Requires Capability Set 2:
uint RWByteAddressBuffer.Load(
    int location,
    out uint status);

/// Requires Capability Set 1:
T RWByteAddressBuffer.Load<T>(uint location);

Generic Parameters

T

The type of the value to load from the buffer.

Parameters

location : int

The input address in bytes, which must be a multiple of 4.

status : uint

[out] The status of the operation.

location : uint

The input address in bytes, which must be a multiple of 4.

Return value

The value loaded from the buffer.

Remarks

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.
