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