It depends on the particular library implementation. It is not a C++ specific question. As far as C++ is concerned, it is just a function call, just like a call to printf or even exit is a function call.
One could be a call to wait for an event.
One could be a call to sleep for a specified period of time.
One could be a call to burn CPU cycles for a specified period of time.
Again, it all depends on the library implementation, and you need to read the documentation for your library to answer this one.
