File descriptor event base class.

Input/output events.

• in = EPOLLIN
• out = EPOLLOUT
• hup = EPOLLHUP | EPOLLRDHUP
• err = EPOLLERR
• inout = EPOLLIN | EPOLLOUT
• def = EPOLLRDHUP | EPOLLET

File descriptor event wrapper for event_poller.

Base classes

• public poll_event_base

Methods

• operator!() const -> bool

  Returns true, if either file descriptor is invalid, or a bad event occurred.

• operator bool() constexplicit

  Returns true, if file descriptor is valid and no bad events occurred.

• operator<(const epoll_event & rhs) const -> bool

  Compares file descriptors.

• operator!=(const epoll_event & rhs) const -> bool

  Returns true, if events have different file descriptors.

• operator==(const epoll_event & rhs) const -> bool

  Returns true, if events have the same file descriptor.

• probe() const -> ssize_t

  Probe file descriptor by peeking a byte from it.

• unsetev(event rhs) -> void

  Unset events rhs in event mask.

• setev(event rhs) -> void

  Set events rhs in event mask.

• bad() const -> bool

  Returns true, if an error or hang up occurred.

• err() const -> bool

  Returns true, if an error occurred.

• hup() const -> bool

  Returns true, if hang up event occurred (the other end of the channel was closed).

• out() const -> bool

  Returns true, if output event occurred.

• in() const -> bool

  Returns true, if input event occurred.

• bad_fd() const -> bool

  Returns true, if file descriptor is invalid.

• disable() -> void

  Disable polling by setting file descriptor to -1.

• fd() const -> fd_type

  Get file descriptor.

• events() const -> E

  Get event mask.

• operator=(const epoll_event &) -> epoll_event &

  Assignment.

• ~epoll_event()
• epoll_event(fd_type f, event ev)

  Construct object from file descriptor f and event mask ev.

• epoll_event()

Friends

• operator<<

  Output file descriptor and event mask for debugging.

Output file descriptor and event mask for debugging.
