Model Types

spin_rw_mutex and queuing_rw_mutex model the ReaderWriterMutex Concept.

ReaderWriterMutex()

Effect: constructs an unlocked ReaderWriterMutex.

~ReaderWriterMutex()

Effect: destroys an unlocked ReaderWriterMutex. The effect of destroying a locked ReaderWriterMutex is undefined.

ReaderWriterMutex::scoped_lock()

Effect: constructs a scoped_lock object that does not hold a lock on any mutex.

ReaderWriterMutex::scoped_lock( ReaderWriterMutex& rw, bool write=true)

Effect: constructs a scoped_lock object that acquires a lock on mutex rw. The lock is a writer lock if write is true; it is a reader lock otherwise.

ReaderWriterMutex::~scoped_lock()

Effect: if the object is holding a lock on a ReaderWriterMutex, releases the lock.

void ReaderWriterMutex:: scoped_lock:: acquire( ReaderWriterMutex& rw, bool write=true)

Effect: acquires a lock on mutex rw. The lock is a writer lock if write is true; it is a reader lock otherwise.

bool ReaderWriterMutex:: scoped_lock::try_acquire( ReaderWriterMutex& rw, bool write=true)

Effect: attempts to acquire a lock on mutex rw. The lock is a writer lock if write is true; it is a reader lock otherwise.

Returns: true if the lock is acquired, false otherwise.

voidReaderWriterMutex:: scoped_lock::release()

Effect: releases the lock. The effect is undefined if no lock is held.

bool ReaderWriterMutex:: scoped_lock::upgrade_to_writer()

Effect: changes a reader lock to a writer lock. The effect is undefined if the object does not already hold a reader ...
