*libports* is a convenience library for easier handling of [[Mach
ports|microkernel/mach/port]]. It is documented in the [[Reference_Manual]].
*libports* is not (at least, not for now) a generalization / abstraction of
Mach ports to the functionality the Hurd needs, that is, it is not meant to
provide an interface independently of the underlying [[microkernel]].
*libports* does not itself depend on *[[libthreads]]*, but the appropriate
threading hooks are used if present, that is if *[[libthreads]]* is used by
another component.
# Message Processing
## `ports_manage_multithreaded`
When a message is recieved, the thread acting as receiver checks if any other
thread is also waiting for requests. If there is none, a new thread is
spawned. Thus, the current thread continues processing the message while the
newly created thread starts listening for new ones. ([[!taglink
open_issue_hurd]]: [[open_issues/multithreading]].)
Also, there are configurable timeouts for [[translator]]s who want to go away
when they are not used. ([[!taglink open_issue_hurd]]: there used to be bugs
in this area, [[!message-id "87hev152we.fsf@becket.becket.net"]], but it may be
fixed as of [[!message-id "20111030210045.GA4983@myhost"]],
