I'm trying to have several threads synced with a boost::barrier. But I'm finding its design very limiting (or, more likely, my understanding of its use is too poor). I want to have a barrier created dynamically (based on some parameters that determine how many threads run). And I also want to be able to delete the barrier at any point in time (from a thread that does not wait on the barrier). I expect this to force all threads that are waiting on the barrier to continue (ie. send a notify_all). However, boost::barrier's destructor just does nothing, so I get a hang. What's the right way to achieve this? PS. On a separate note... is there any reason why all of boost primitives have their variables private? I really would find it pretty useful to sometimes be able to query, for example, the lock count of some objects. -- Gonzalo Garramuño ggarra@advancedsl.com.ar AMD4400 - ASUS48N-E GeForce7300GT Xubuntu Gutsy
