Unable to Set Thread Name with pthread_setname_np on Windows 11

[quicsam]

Hi vcpkg team,

I am using vcpkg to install pthread.h in an intel windows 11 machine. However, the pthread_setname_np function provided by this package does not actually set the name of the thread.

I understand that the native API for threads is processthreadsapi.h. But I wanted to know if there a way to set the thread name using functions in pthread.h?

Any suggestions/workarounds would be helpful.

Thank you.

The pthread_setname_np function is not natively supported on Windows in the same way it is on Linux. This is because Windows uses a different threading model, and the pthread.h implementation on Windows (like the one provided by vcpkg) is often a compatibility layer that doesn't fully replicate all POSIX thread features.

To set a thread name on Windows, you can use the native Windows API function SetThreadDescription, which is available starting from Windows 10, version 1607. Unfortunately, this is outside the scope of pthread.h.
