It requires you to say when
separate threads should be started, but apart from that the flow of
data is handled transparently -- threads will suspend until a value
they need becomes available.

Not really.
It's just that library functions may spawn their own threads when
needed, but that doesn't mean you don't have t
intelligent way, based upon information
added to the object in order to be thread-safe, creating threads if it
can or just jumping to another task if something is too slow..
Well I know this is not serious.. ;) but it
urd itself. The Hurd could make
use of such a functionality and replace threads usage with your new thing if
it existed. But it doesn't, so we don't worry about it. Implementing such is
not the focus of the Hurd project at all.
Also, it doesn't do away with the need for pthreads s
Just a final note.
Mabye you are not interested in *completely* transparent threading?
Mabye you just would like threads to be managed by the OS wherever it might

Start to check out BeOS. I don't really know much about Be, but it claims to
do just this, so it might be worth a
f hidden mutexes
and such, but I think this breaks something in the C spec, and you would
probably end up with an incredibly inefficient code.
So, the first thing you'll have to do, is just to design a new
byte-granular-MMU,
a new microprocessor that manages function calls as threads and handles the

Hi Roberto,
I sense the frustration in your request so I'll attempt to set your mind
at ease if I can. As someone mentioned:
1) they're a readily understood programming concept
also:
2) cthreads are already implemented
3) time and manpower
4) the structure of the hurd project
I think the

Can somebody tell me what is the need to keep having that abstraction?
Why do we really need threads?
For expample..
1.-In a single-proccesor machine.
Hi Nasos
The hurd uses cthreads at this time. There are plans to implement pthreads
but that is at some time in the future.

Hi,
Is there a pthread implementation for
the Hurd? If not are there any other
libraries to provide thread support
for applications?
Thanks,
Nasos
