Overview

Returned by SleepyPenguin::Inotify#take. It is a Struct with the following elements:

  • wd - watch descriptor (unsigned Integer)

  • mask - mask of events (unsigned Integer)

  • cookie - unique cookie associated related events (for rename)

  • name - optional string name (may be nil)

The mask is a bitmask of the event flags accepted by Inotify#add_watch and may also include the following flags:

  • :IGNORED - watch was removed

  • :ISDIR - event occured on a directory

  • :Q_OVERFLOW - event queue overflowed (wd is -1)

  • :UNMOUNT - filesystem containing watched object was unmounted

Use the Event#events method to get an array of symbols for the matched events.
