Please have a look into the test residing in libports/src/test/libc_component.
That looks indeed close to what I want to have. What is not clear to me why _select_ready is registered as handler but then still called manually after Select_handler::select returns.
Sorry for being nitpicky, I just want to get a better understanding about this (my understanding of the whole Libc interface also could be better so this is a starting point).
No problem. It is registered as handler function for the case the entrypoint was blocked when the fd becomes readable. But, (like in POSIX) Select_handler::select() may also return immediately with readable fds, which should also be handled immediately. I remember distantly that otherwise a deblocked fd ended up unhandled in some edge cases.
