RWByteAddressBuffer.InterlockedCompareStore¶

Description¶

Perform a 32-bit integer atomic compare-and-store operation at the specified byte address within the RWByteAddressBuffer.

Signature¶

void RWByteAddressBuffer.InterlockedCompareStore(
    uint dest,
    uint compare_value,
    uint value);

Parameters¶

dest : uint¶

The address at which to perform the atomic add operation.

compare_value : uint¶

The value to perform comparison to the value at byteAddress.

value : uint¶

The value to store at byteAddress if the comparison is successful.

Remarks¶

For SPIR-V, this function maps to OpAtomicCompareExchange. For HLSL, this function translates to InterlockedCompareStore. For CUDA, this function maps to atomicCAS.
