Standard library header <thread>

< cpp‎ | header

This header is part of the thread support library.



manages a separate thread


specializes the std::swap algorithm
(function template)
compares two thread::id objects
serializes a thread::id object
(function template)
specializes std::hash
(class template specialization)


this_thread provide functions that access current the thread of execution
Defined in namespace std::this_thread
suggests that the implementation reschedule execution of threads
returns the thread id of the current thread
stops the execution of the current thread for a specified time duration
stops the execution of the current thread until a specified time point
