Thread support library

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 list 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.

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