I'm assuming epoll is covered implicitly by the section on kqueue. Are there any differences between the two besides the name?

- toast0 1y agoepoll returns a single value for events, and kqueue returns a struct. typedef union epoll_data { void *ptr; int fd; uint32_t u32; uint64_t u64; } epoll_data_t; vs struct kevent { uintptr_t ident; /* identifier for this event */ short filter; /* filter for event */ u_short flags; /* action flags for kqueue */ u_int fflags; /* filter flag value */ int64_t data; /* filter data value */ void *udata; /* opaque user data identifier */ uint64_t ext[4]; /* extensions */ }; For read/write events, ident is the FD and data is the number of bytes that can be read or written.
