I am new to std::thread. I need to put a std::thread to sleep from another thread, is that possible? In examples, all I see is code like:
std::this_thread::sleep_for(std::chrono::seconds(1));
But what I want to do is something like:
std::thread t([]{...});
t.sleep(std::chrono::seconds(1));
or
sleep(t, std::chrono::seconds(1));
Any ideas?
Because sleep_for is synchronous, it only really makes sense in the current thread. What you want is a way to suspend / resume other threads. The standard does not provide a way to do this (afaik), but you can use platform-dependent methods using native_handle.
For example on Windows, SuspendThread and ResumeThread.
But more important is that there is almost never a need to do this. Usually when you encounter basic things you need that the standard doesn't provide, it's a red flag that you're heading down a dangerous design path. Consider accomplishing your bigger goal in a different way.
