Functions

func CloseOnExec

func CloseOnExec(fd int32)

func EpollCreate1

func EpollCreate1(flags int32) (fd int32, errno uintptr)

func EpollCtl

func EpollCtl(epfd, op, fd int32, event *EpollEvent) (errno uintptr)

func EpollWait

func EpollWait(epfd int32, events []EpollEvent, maxev, waitms int32) (n int32, errno uintptr)
