I want to know if gnu g++'s STL implementation is thread safe or not. If it's not thread safe I want to know hou you deal with the problem of multithreading.
Initially I suppose that protecting all access to an STL containter with mutexes, I can resolve the problem, but I have a doubt about it: Memory allocation. I can protect with a mutex access to a resource (for example an STL container), but the default allocator can be accessed concurrently from several containers and/or instances of a concrete container, and I haven't the control of it. There are other techniques for efficiency, as sharing implementation (with reference counting) that I suppose that can have problems with multithreading but I don't know if g++'s STL implementation uses that kind of techniques. Thanks in advance. _______________________________________________ help-gplusplus mailing list help-gplusplus@gnu.org http://lists.gnu.org/mailman/listinfo/help-gplusplus
