Detailed Description

template<class CompletionFunction = barrier_default_completion>
class Chusov::ExecutionControl::barrier< CompletionFunction >

Implements a reusable barrier synchronization primitive.

Template Parameters

CompletionFunction

Specifies a class implementing functional objects called without parameters upon opening of barriers. The default functional object is barrier_default_completion which performs no actions.

Implements a C++20 std::barrier interface using C++14.

A single-use barrier is also implemented by the latch class.
