This header is part of the thread support library.

Classes
rcu_obj_base (C++26)	allows an object to be protected by RCU (class template)
rcu_domain (C++26)	provides regions of RCU protection (class)
Functions
rcu_default_domain (C++26)	returns a reference to a static-duration object of type std::rcu_domain (function)
rcu_synchronize (C++26)	blocks until a protection region unlocks on a RCU domain (function)
rcu_barrier (C++26)	may evaluate scheduled operations on a RCU domain and blocks until all preceding evaluations are complete (function)
rcu_retire (C++26)	schedules the evaluation of a specified function on a RCU domain, potentially allocating memory, and invoking scheduled evaluations (function template)
