File descriptor event base class.

File descriptor event wrapper for poll(2) system call.

Base classes

• public basic_event

Enumerations

• enum event_type: legacy_event

  Input/output events.

Fields

• decltype(basic_event::events) typedef legacy_event

  Event mask type.

Methods

• operator!() const -> constexpr bool

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

• operator bool() const -> constexprexplicit

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

• operator<(const poll_event & rhs) const -> constexpr bool

  Compares file descriptors.

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

  Returns true, if events have different file descriptors.

• operator==(const poll_event & rhs) const -> constexpr bool

  Returns true, if events have the same file descriptor.

• probe() const -> ssize_t

  Probe file descriptor by peeking a byte from it.

• setall(event_type rhs) -> void

  Set events rhs in event mask and recorded event mask.

• unsetrev(event_type rhs) -> void

  Unset events rhs in recorded event mask.

• setrev(event_type rhs) -> void

  Set events rhs in recorded event mask.

• unsetev(event_type rhs) -> void

  Unset events rhs in event mask.

• setev(event_type rhs) -> void

  Set events rhs in event mask.

• bad() const -> constexpr bool

  Returns true, if an error or hang up occurred.

• err() const -> constexpr bool

  Returns true, if an error occurred.

• hup() const -> constexpr bool

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

• out() const -> constexpr bool

  Returns true, if output event occurred.

• in() const -> constexpr bool

  Returns true, if input event occurred.

• bad_fd() const -> constexpr bool

  Returns true, if file descriptor is invalid.

• fd() const -> constexpr fd_type

  Get file descriptor.

• disable() -> void

  Disable polling by setting file descriptor to -1.

• events() const -> constexpr legacy_event

  Get event mask.

• revents() const -> constexpr legacy_event

  Get recorded event mask.

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

  Assignment.

• poll_event(fd_type f = -1, legacy_event ev = 0, legacy_event rev = 0) -> constexprexplicit

  Construct object from file descriptor f, event mask ev and recorded events rev.
