Anything not in the pthreads api wouldn't be portable.  Some implementations
like Linux have that info in userspace if you can figure out your way through
the opaque data types to get to it but I wouldn't trust the api to be stable
enough that you could trust code to work accross multiple releases.  And there
is no such thing as a standard pthread syscall if you're thinking there's
anything like that.
