[Boost-users] boost interprocess named_mutex: race condition at creation?

Hi, I am using named_mutex for synchronization among multiple processes. If all of the processes try to open_or_create the same-name named_mutex: named_mutex mutex(open_or_create, "somename"); 1) Is there any race condition for mutex creation? Or the API will guarantee one will create and all others will open? 2) If there is race condition, what are the work-arounds for this on Linux? Thanks, Liwei
