Detailed Description

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.

Constructor & Destructor Documentation

boost::interprocess::named_condition_any::named_condition_any	(	create_only_t	,
		const char *	name,
		const permissions &	perm = `permissions()`
	)

inline

Creates a global condition with a name.

If the condition can't be created throws interprocess_exception

boost::interprocess::named_condition_any::named_condition_any	(	open_or_create_t	,
		const char *	name,
		const permissions &	perm = `permissions()`
	)

inline

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

boost::interprocess::named_condition_any::named_condition_any	(	open_only_t	,
		const char *	name
	)

inline

Opens a global condition with a name if that condition is previously created.

If it is not previously created this function throws interprocess_exception.

boost::interprocess::named_condition_any::~named_condition_any ( )

inline

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().

Member Function Documentation

void boost::interprocess::named_condition_any::notify_all ( )

inline

Change the state of all threads waiting on *this to ready.

If there are no waiting threads, notify_all() has no effect.

References boost::interprocess::ipcdetail::shm_named_condition_any::notify_all().

* void boost::interprocess::named_condition_any::notify_one ( )

inline

If there is a thread waiting on *this, change that thread's state to ready.

Otherwise there is no effect.

References boost::interprocess::ipcdetail::shm_named_condition_any::notify_one().

static bool boost::interprocess::named_condition_any::remove ( const char * name )

inlinestatic

Erases a named condition from the system.

Returns false on error. Never throws.

References boost::interprocess::ipcdetail::shm_named_condition_any::remove().

template<typename L >

bool boost::interprocess::named_condition_any::timed_wait	(	L &	lock,
		const boost::posix_time::ptime &	abs_time
	)

inline

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.

References boost::interprocess::ipcdetail::shm_named_condition_any::timed_wait().

template<typename L , typename Pr >

bool boost::interprocess::named_condition_any::timed_wait	(	L &	lock,
		const boost::posix_time::ptime &	abs_time,
		Pr	pred
	)

inline

The same as: while (!pred()) { if (!timed_wait(lock, abs_time)) return pred(); } return true;.

References boost::interprocess::ipcdetail::shm_named_condition_any::timed_wait().

template<typename L >

void boost::interprocess::named_condition_any::wait ( L & lock )

inline

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.

References boost::interprocess::ipcdetail::shm_named_condition_any::wait().

template<typename L , typename Pr >

void boost::interprocess::named_condition_any::wait	(	L &	lock,
		Pr	pred
	)

inline

The same as: while (!pred()) wait(lock)

References boost::interprocess::ipcdetail::shm_named_condition_any::wait().
