C++ and posix threads

[Jean-Marc Bourguet <jm@xxxxxxxxxxxx>]

I feel confused.  I wonder what is the context of the discussion
and especially the constraints or the liberties we assume from
an implementation.  Shoult it
   - need the collaboration of the pthread library or be implementable
     as wrapper around an existing pthread library?
   - allow modifications to the C interface visible from C or not?
   - allow modifications to the C interface visible from C++ or not?

Answering those questions will more or less strongly constraints the rest
of the discussion.

I didn't saw these issues discussed in the archive (if I missed them please
point me to the discussion) and it seems to me that people are assuming
different positions on them (Ted Baker seems to assume that it will be
a wrapper around an existing pthread library without modifications seen
to C code while Nathan Myers's proposition to return an ECANCELED error
imply afaik the collaboration of the pthread library and modification
to the C interface and Alexander Terekhov is apparently somewhere in between
them along this space).

Yours,
