This header is part of the thread support library.

Classes
thread (C++11)	manages a separate thread (class)
Functions
std::swap(std::thread) (C++11)	specializes the std::swap algorithm (function template)
operator==operator!=operator< operator<= operator> operator>=	compares two thread::id objects (function)
operator<<	serializes a thread::id object (function template)
std::hash<std::thread::id>	specializes std::hash (class template specialization)
Namespaces
this_thread	provide functions that access current the thread of execution
Functions
Defined in namespace std::this_thread
yield (C++11)	suggests that the implementation reschedule execution of threads (function)
get_id (C++11)	returns the thread id of the current thread (function)
sleep_for (C++11)	stops the execution of the current thread for a specified time duration (function)
sleep_until (C++11)	stops the execution of the current thread until a specified time point (function)
