A global condition variable that can be created by name. This condition variable is designed to work with named_mutex and can't be placed in shared memory or memory mapped files.
named_condition_any
public
construct/copy/destruct(create_only_t, name, permissions & perm = permissions());
Creates a global condition with a name. If the condition can't be created throws interprocess_exception
(open_or_create_t, name, permissions & perm = permissions());
Opens or creates a global condition with a name. If the condition is created, this call is equivalent to named_condition_any(create_only_t, ... ) If the condition is already created, this call is equivalent named_condition_any(open_only_t, ... ) Does not throw
(open_only_t, name);
Opens a global condition with a name if that condition is previously created. If it is not previously created this function throws interprocess_exception
.
(create_only_t, name, permissions & perm = permissions());
Creates a global condition with a name. If the condition can't be created throws interprocess_exception
Note: This function is only available on operating systems with native wchar_t APIs (e.g. Windows).

.

~();
Destroys *this and indicates that the calling process is finished using the resource. The destructor function will deallocate any system resources allocated by the system for use by this process for this resource. The resource can still be opened again calling the open constructor overload. To erase the resource from the system use remove().

public member functions();
If there is a thread waiting on this, change that thread's state to ready. Otherwise there is no effect.<zwj></zwj>/
();
Change the state of all threads waiting on *this to ready. If there are no waiting threads, notify_all() has no effect.
template<typename L> ( lock);
Releases the lock on the named_mutex
object associated with lock, blocks the current thread of execution until readied by a call to this->notify_one() or this->notify_all(), and then reacquires the lock.
template<typename L, typename Pr> ( lock, pred);
The same as: while (!pred()) wait(lock)
template<typename L, typename TimePoint> ( lock, abs_time);
Releases the lock on the named_mutex
object associated with lock, blocks the current thread of execution until readied by a call to this->notify_one() or this->notify_all(), or until time abs_time is reached, and then reacquires the lock. Returns: false if time abs_time is reached, otherwise true.
template<typename L, typename TimePoint, typename Pr> ( lock, abs_time, pred);
The same as: while (!pred()) { if (!timed_wait(lock, abs_time)) return pred(); } return true;
template<typename L, typename TimePoint> ( lock, abs_time);
Same as timed_wait
, but this function is modeled after the standard library interface.
template<typename L, typename TimePoint, typename Pr> ( lock, abs_time, pred);
Same as timed_wait
, but this function is modeled after the standard library interface.
template<typename L, typename Duration> ( lock, dur);
Same as timed_wait
, but this function is modeled after the standard library interface and uses relative timeouts.
template<typename L, typename Duration, typename Pr> ( lock, dur, pred);
Same as timed_wait
, but this function is modeled after the standard library interface and uses relative timeouts
