Overview ¶

Package fdnotifier contains an adapter that translates IO events (e.g., a file became readable/writable) from native FDs to the notifications in the waiter package. It uses epoll in edge-triggered mode to receive notifications for registered FDs.

Functions ¶

func AddFD ¶

func AddFD(fd int32, queue *waiter.Queue) error

AddFD adds an FD to the list of observed FDs.

func HasFD ¶

func HasFD(fd int32) bool

HasFD returns true if the FD is in the list of observed FDs.

This should only be used by tests to assert that FDs are correctly registered.

NonBlockingPoll polls the given FD in non-blocking fashion. It is used just to query the FD's current state.

func RemoveFD(fd int32)

RemoveFD removes an FD from the list of observed FDs.

func UpdateFD ¶

func UpdateFD(fd int32) error

UpdateFD updates the set of events the fd needs to be notified on.
