Btw: i just discovered that pthread mutexes and condvars can have a "process shared" flag which makes it possiblo to synchronize threads across processes as it seems. Could be useful for jack, no? pthread_condvar_setpshared() pthread_mutexattr_setpshared() Or do i misread that manpage? Flo -- Palimm Palimm! http://tapas.affenbande.org
