     [ https://issues.apache.org/jira/browse/XERCESC-42?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Boris Kolpackov closed XERCESC-42.
----------------------------------

    Resolution: Won't Fix
      Assignee:     (was: Xerces-C Developers Mailing List)

To make Initialize() thread-safe we would need a once-initialization mechanism (e.g., PTHREAD_ONCE) but it is platform-dependent and may not be available on some platforms that we support.

> All of the samples assume that we have a simple main() where we can run 
> Initialize() and Terminate(), but in mine it is a multi-threaded shared library 
> (.so, .dll) which has to field requests from multiple connections, of which the 
> usage of xml parsing is part of several tasks. Since I'm trying to minimize 
> resource usage, I would perfer not to Initialize() on startup, but would rather 
> Initialize(), Terminate() around specific events. The code itself says it's not 
> thread-safe.
> Would it be possible for the platfirm to use mutexes, even though this is 
> before the platform initialization?
