can use this? bool owns_lock() const; ------------------ Original ------------------ From: "gast128";<gast128@hotmail.com>; Date: Thu, Jun 26, 2014 07:46 PM To: "boost-users"<boost-users@lists.boost.org>; Subject: [Boost-users] [thread] mutex is locked Dear all, does anybody know if there is a possibility to check if a mutex is locked? There is an 'owns_lock' on the lock type but not on the mutex. The main use case for me is debugging (and documentation) purposes: void MyClass::Process() { boost::unique_lock<boost::mutex> lck(m_mtx); ProcessImpl(); } void MyClass::ProcessImpl() { _ASSERT(m_mtx.is_locked()); //does not exist :( } _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users .
