If user threading under linux compatibility is still implemented using fork(2), then you'll have a process per user thread. In that case it doesn't matter how threading is natively implemented. So, if fork(2) is the basis for threading, return td->td_proc->p_pid, otherwise you probably want to return td->td_tid. -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
