Contents

Threads

Threads enable the program to execute across several processor cores.

Mutual exclusion

Mutual exclusion algorithms restrict access to a shared resource so that only one thread can access it at a time. This allows to avoid data races and to implement synchronization between threads.

Condition variables

A condition variable is a synchronization primitive which implements a queue of threads that are waiting until another thread notifies one or all of the waiting threads that they may proceed, until a timeout expires, or until a spurious wakeup occurs. A condition variable is always associated with a mutex.

provides a condition variable assocaited with std::unique_lock
(class)
provides a condition varibale associated with any lock type
(class)
schedules a call to notify_all to be invoked when this thread exits
(function)
(C++11)
lists the possible results of timed waits on condition variables
(class)

Futures

Defined in header <future>
(C++11)
stores a value for asynchronous retrieval
(class template)
packages a function to store its return value for asynchronous retrieval
(class template)
(C++11)
waits for a value that is set asynchronously
(class template)
waits for a value that is set asynchronously. The internal state is shared among several objects
(class template)
(C++11)
provides a facility to launch a function in a new thread and acquire its return value asynchronously
