For the most of the cases when API is not a cancellation point it is easy to make NX API as a system call and create a libc wrapper that will handle `errno` correctly. The real problem is cancellation point APIs (the APIs that pend). The cancellation point enter/leave should be executed n kernel mode, so I do not see any other option that creating a two variants of the same API that differ only with cancellation point management and expose both as system calls. Again that contradicts assumption that only POSIX APIs are a system calls. Anyway we already have many NX APIs as system calls, so I think we can make whatever is convenient to be used. -- This is an automated message from the Apache Git Service.
