Question

InterlockedCompareExchange128 is not found on newer sdk

Alexandra Wheeler 0

I'm running into a problem using windows 11 sdk (10.0.22621.0) through Microsoft Visual Studio. However I'm running into a problem where it cannot find "InterlockedCompareExchange128".

The specific error message looks like:
error C3861: 'InterlockedCompareExchange128': identifier not found

It can find InterlockedCompareExchange64, but not InterlockedCompareExchange128. I've previously used windows 10 sdk (10.0.18362.0) where everything worked.

Maybe you are using the “x86” configuration instead of “x64”.

According to the Doc:InterlockedCompareExchange128 function

This function is only available on x64-based systems, and it is implemented using a compiler intrinsic.
