interprocess_sharable_mutex(const interprocess_sharable_mutex &);

interprocess_sharable_mutex();

Constructs the sharable lock. Throws interprocess_exception on error.

interprocess_sharable_mutex & operator=(const interprocess_sharable_mutex &);

~interprocess_sharable_mutex();

Destroys the sharable lock. Does not throw.

void lock();

Effects: The calling thread tries to obtain exclusive ownership of the mutex, and if another thread has exclusive or sharable ownership of the mutex, it waits until it can obtain the ownership. Throws: interprocess_exception on error.

bool try_lock();

Effects: The calling thread tries to acquire exclusive ownership of the mutex without waiting. If no other thread has exclusive or sharable ownership of the mutex this succeeds. Returns: If it can acquire exclusive ownership immediately returns true. If it has to wait, returns false. Throws: interprocess_exception on error.

bool timed_lock(const boost::posix_time::ptime & abs_time);

Effects: The calling thread tries to acquire exclusive ownership of the mutex waiting if necessary until no other thread has exclusive or sharable ownership of the mutex or abs_time is reached. Returns: If acquires exclusive ownership, returns true. Otherwise returns false. Throws: interprocess_exception on error.

void unlock();

Precondition: The thread must have exclusive ownership of the mutex. Effects: The calling thread releases the exclusive ownership of the mutex. Throws: An exception derived from interprocess_exception on error.

void lock_sharable();

Effects: The calling thread tries to obtain sharable ownership of the mutex, and if another thread has exclusive ownership of the mutex, waits until it can obtain the ownership. Throws: interprocess_exception on error.

bool try_lock_sharable();

Effects: The calling thread tries to acquire sharable ownership of the mutex without waiting. If no other thread has exclusive ownership of the mutex this succeeds. Returns: If it can acquire sharable ownership immediately returns true. If it has to wait, returns false. Throws: interprocess_exception on error.

bool timed_lock_sharable(const boost::posix_time::ptime & abs_time);

Effects: The calling thread tries to acquire sharable ownership of the mutex waiting if necessary until no other thread has exclusive ownership of the mutex or abs_time is reached. Returns: If acquires sharable ownership, returns true. Otherwise returns false. Throws: interprocess_exception on error.

void unlock_sharable();

Precondition: The thread must have sharable ownership of the mutex. Effects: The calling thread releases the sharable ownership of the mutex. Throws: An exception derived from interprocess_exception on error.
