The ThreadHint parameter can be used to request, but not guarantee, that a task executes on a particular thread. The value passed should be the integer index in range [0..ThreadCount) of the thread in that executor. You can retrieve the current thread index using tmc::current_thread_index().

tmc::post_bulk()

template<typename E, typename Iter, typename TaskOrFunc = std::iter_value_t<Iter>>
void tmc::post_bulk(E &Executor, Iter &&Begin, size_t Count, size_t Priority = 0, size_t ThreadHint = NO_HINT)

Iter must be an iterator type that implements operator*() and Iter& operator++(). The type of the items in Iter must be task<void> or a type implementing void operator().

Submits items in range [Begin, Begin + Count) to the executor at priority Priority.
