Suppose we have an epoll file descriptor that is monitoring, Ask an Expert

Engineering

Suppose we have an epoll file descriptor that is monitoring multiple file descriptors, all of which are always ready. If we perform a series of epoll_wait() calls in which maxevents is much smaller than the number of ready file descriptors (e.g., maxevents is 1), without performing all possible I/O on the ready descriptors between calls, what descriptor(s) does epoll_wait() return in each call? Write a program to determine the answer. (For the purposes of this experiment, it suffices to perform no I/O between the epoll_wait() system calls.) Why might this behavior be useful?
