Ran into something that AFAICT is amiss in the interprocess docs. In various places it says: "If a thread takes ownership of the mutex the mutex must be unlocked by the same mutex." Should that instead say: "If a thread takes ownership of the mutex the mutex must be unlocked by the same thread." Note, the last word. Or is the locking and unlocking at the process level, instead of at the thread level? Meaning should it instead read: "If a process takes ownership of the mutex the mutex must be unlocked by the same process." -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org (msn) - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim,yahoo,skype,efnet,gmail
