class recursive_mutex

• Member functions
  • recursive_mutex()
  • recursive_mutex( const recursive_mutex& ) = delete
    Constructs the mutex. The mutex is in unlocked state after the call.
    Copy constructor is deleted.
  • void lock()
    Locks the mutex. If another fiber has already locked the mutex, a call to lock will block execution until the lock is acquired.
    A fiber may call lock on a recursive mutex repeatedly. Ownership will only be released after the fiber makes a matching number of calls to unlock.
  • bool try_lock()
    Tries to lock the mutex. Returns immediately. On successful lock acquisition returns true, otherwise returns false.
    If try_lock is called by a fiber that already owns the mutex, it always returns true.
    A fiber may call try_lock on a recursive mutex repeatedly. Successful calls to try_lock increment the ownership count: the mutex will only be released after the fiber makes a matching number of calls to unlock.
  • void unlock()
    Unlocks the mutex if its level of ownership is 1 (there was exactly one more call to lock() than there were calls to unlock() made by this fiber), reduces the level of ownership by 1 otherwise.
    The mutex must be locked by the current fiber of execution, otherwise an operation_not_permitted error condition may be thrown.
