Subject: [Boost-users] upgrading lock

Hello,
Just wanted to be sure that I'm doing this correctly.
typedef boost::upgrade_lock<boost::shared_mutex> upgrade_lock;
typedef boost::upgrade_to_unique_lock<boost::shared_mutex>
upgrade_to_unique_lock;
upgrade_lock readLock(mutex_);
// accessing shared resources in read-only mode
//...
upgrade_to_unique_lock writeLock(readLock);
// modifying shared resources
Is the above correct? In particular, upgrade_lock acquires "read" lock
in raii style (similarly to shared_lock), right?
Thanks.
