DESCRIPTION

The iv_inotify_register function registers an iv_inotify instance with the iv_inotify(3) module. The inotify parameter is a pointer to the iv_inotify structure to be registered.

The iv_inotify_unregister function unregisters an iv_inotify instance from the iv_inotify(3) module. The inotify parameter is a pointer to the iv_inotify structure to be unregistered.

The iv_inotify_watch_register function adds a watch to the registered iv_inotify instance specified by the ->inotify member.

The iv_inotify_watch_unregister function removes a watch from the iv_inotify instance specified by the ->inotify member.

In the iv_inotify_watch structure used in these functions, the ->pathname and ->mask members correspond to the members of struct inotify_watch as described in inotify(7). ->handler is the event handler called when this watch triggers. The arguments to this handler function are the pointer stored in the ->cookie member of the iv_inotify_watch structure and a pointer to an inotify_event structure as described in inotify(7).

RETURN VALUE

iv_inotify_register and iv_inotify_watch_register return zero on success. On error, -1 is returned, and errno is set appropriately.
