O_CLOEXEC is defined differently for each architecture, so we need to stay out of several different bits when we define new flags for EPOLL_*. Maybe this: /* * Flags for epoll_create1. O_CLOEXEC may be different bits, depending * on the CPU architecture. Reserve the known ones. */ #define EPOLL_CLOEXEC O_CLOEXEC #define EPOLL_RESERVED_FLAGS 0x00680000 #define EPOLL_NSTIMEO 0x00000001
