kqueue.fileno() Return the file descriptor number of the control fd.

kqueue.control(changelist, max_events[, timeout=None]) → eventlist Low level interface to kevent changelist must be an iterable of kevent object or None max_events must be 0 or a positive integer timeout in seconds (floats possible) Changed in version 3.5: The function is now retried with a recomputed timeout when interrupted by a signal, except if the signal handler raises an exception (see PEP 475 for the rationale), instead of raising InterruptedError.

kqueue.closed True if the kqueue object is closed.

kqueue.close() Close the control file descriptor of the kqueue object.

select.kqueue() (Only supported on BSD.) Returns a kernel queue object; see section Kqueue Objects below for the methods supported by kqueue objects. The new file descriptor is non-inheritable. Changed in version 3.4: The new file descriptor is now non-inheritable.

kevent.udata User defined value.

kevent.ident Value used to identify the event. The interpretation depends on the filter but it’s usually the file descriptor. In the constructor ident can either be an int or an object with a fileno() method. kevent stores the integer internally.

kevent.flags Filter action. Constant Meaning KQ_EV_ADD Adds or modifies an event KQ_EV_DELETE Removes an event from the queue KQ_EV_ENABLE Permitscontrol() to returns the event KQ_EV_DISABLE Disablesevent KQ_EV_ONESHOT Removes event after first occurrence KQ_EV_CLEAR Reset the state after an event is retrieved KQ_EV_SYSFLAGS internal event KQ_EV_FLAG1 internal event KQ_EV_EOF Filter specific EOF condition KQ_EV_ERROR See return values

kevent.filter Name of the kernel filter. Constant Meaning KQ_FILTER_READ Takes a descriptor and returns whenever there is data available to read KQ_FILTER_WRITE Takes a descriptor and returns whenever there is data available to write KQ_FILTER_AIO AIO requests KQ_FILTER_VNODE Returns when one or more of the requested events watched in fflag occurs KQ_FILTER_PROC Watch for events on a process id KQ_FILTER_NETDEV Watch for events on a network device [not available on Mac OS X] KQ_FILTER_SIGNAL

kevent.fflags Filter specific flags. KQ_FILTER_READ and KQ_FILTER_WRITE filter flags: Constant Meaning KQ_NOTE_LOWAT low water mark of a socket buffer KQ_FILTER_VNODE filter flags: Constant Meaning KQ_NOTE_DELETE unlink() was called KQ_NOTE_WRITE a write occurred KQ_NOTE_EXTEND the file was extended KQ_NOTE_ATTRIB an attribute was changed KQ_NOTE_LINK the link count has changed KQ_NOTE_RENAME the file was renamed KQ_NOTE_REVOKE access to the file was revoked KQ_FILTER_PROC filter flags:
