Are atomic_* implementations allowed to spin/sleep? The question is because some platforms don't have atomic operations for adding and so on (e.g. sparcv8). The only way to implement them on these platforms is to use a lock. Now I'm wonder if the use of a sleep mutex is allowed or is a simple spinning lock the sensefull choice. One of the results is that there is no mutex/lock allocated specially for this purpose and there is a need to allocate one globaly for all. -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
