time_point( const time_point<Clock, Duration2>& t ); (C++11 起) (C++14 起为 constexpr) 从数个可选数据源之一构造新的 time_point。 1) 默认构造函数,创建表示 Clock 的纪元(即 time_since_epoch() 为零)的 time_point。2) 构造位于 Clock 的纪元加上 d 的time_point。3...

If you want to set the thread count at runtime, there is no convenient way... But here is how.svr.new_task_queue = [] { return new ThreadPool(12); }; You can also provide an optional parameter to limit the maximum number of pending requests, i.e. requests accept()ed by the ...
However, the cases should be fairly obvious: any time an element needs to appear multiple times (as in combinations or cycle) or be looked at more than once (specifically, sorted). This library takes every effort to rely on as little as possible from the underlying iterables, but if ...
