[Boost-users] [boost-users][thread] upgrading lock

Hello,

This's rather basic question, but I couldn't find any example in the docs.

typedef boost::shared_lock<boost::shared_mutex> shared_lock;
shared_mutex mutex_;
///
{
  shared_lock lock(mutex_);
  // reading locked data...

  // here I want to midify the data, how can I upgrade the lock to be exclusive?
}

Thank you in advance.
