Implement missing functions on windows

[lplewa]

Missing functions on windows should be implemented, and just return not supported return code. Currently, we just do not export some linux only functions on windows.

Which API do you mean? Do we have a list?

I think we should only ifdef things that will never work on Windows or use nix-specific things (like file descriptors). Things that are currently unimplemented (but will be eventually) should just fail at runtime.

This is also an option. ATM we just do not provide symbol which is just bad

since this is about .def and .map files - isn't this related to/duplicate of https://github.com/oneapi-src/unified-memory-framework/issues/566 ?

No - this is only similar issue:

• those issue is about functions which was exported, but are not supposed to be exported. (internal function)
• this issue is about functions which are supposed to be exported but there are not

umfLevelZeroMemoryProviderOps

LevelZero provider should be supported on Windows.
