Event flags

Event::READ This flag indicates an event that becomes active when the provided file descriptor (usually a stream resource, or socket) is ready for reading.

Event::WRITE flag indicates an event that becomes active when the provided file descriptor (usually a stream resource, or socket) is ready for writing.

Event::SIGNAL used to implement signal detection. See "Constructing signal events" below.

Event::TIMEOUT indicates an event that becomes active after a timeout elapses. The Event::TIMEOUT flag is ignored when constructing an event: one can either set a timeout when event is added, or not. It is set in the $what argument to the callback function when a timeout has occurred.
