With that said, I would like to ask that you refrain from making such ignorant comments, or better yet, that you use Windows. Software developers don't have time to deal with this nonsense.

I must have completely misunderstood your post / OP, but pthread_self returns the current thread ID.
Beyond that, as far as I can see gettid is exported to usermode (by using syscall(SYS_gettid)).
Did I miss anything?
