Classes

allows an object to be protected by RCU
(class template) [edit]
provides regions of RCU protection
(class) [edit]

Functions

returns a reference to a static-duration object of type std::rcu_domain
(function) [edit]
blocks until a protection region unlocks on a RCU domain
(function) [edit]
may evaluate scheduled operations on a RCU domain and blocks until all preceding evaluations are complete
(function) [edit]
schedules the evaluation of a specified function on a RCU domain, potentially allocating memory, and invoking scheduled evaluations
(function template) [edit]
