abstractmethod get_map() Return a mapping of file objects to selector keys. This returns a Mapping instance mapping registered file objects to their associated SelectorKey instance.

close() Close the selector. This must be called to make sure that any underlying resource is freed. The selector shall not be used once it has been closed.

select.poll.register()

poll.register(fd[, eventmask]) Register a file descriptor with the polling object. Future calls to the poll() method will then check whether the file descriptor has any pending I/O events. fd can be either an integer, or an object with a fileno() method that returns an integer. File objects implement fileno(), so they can also be used as the argument. eventmask is an optional bitmask describing the type of events you want to check for, and can be a combination of the constants POLLIN, POLLPR

select.poll.unregister()

poll.unregister(fd) Remove a file descriptor being tracked by a polling object. Just like the register() method, fd can be an integer or an object with a fileno() method that returns an integer. Attempting to remove a file descriptor that was never registered causes a KeyError exception to be raised.

select.poll()

select.poll() (Not supported by all operating systems.) Returns a polling object, which supports registering and unregistering file descriptors, and then polling them for I/O events; see section Polling Objects below for the methods supported by polling objects.

select.poll.modify()

poll.modify(fd, eventmask) Modifies an already registered fd. This has the same effect as register(fd, eventmask). Attempting to modify a file descriptor that was never registered causes an OSError exception with errno ENOENT to be raised.

select.poll.poll()

poll.poll([timeout]) Polls the set of registered file descriptors, and returns a possibly-empty list containing (fd, event) 2-tuples for the descriptors that have events or errors to report. fd is the file descriptor, and event is a bitmask with bits set for the reported events for that descriptor — POLLIN for waiting input, POLLOUT to indicate that the descriptor can be written to, and so forth. An empty list indicates that the call timed out and no file descriptors had any events to report

select.select()

select.select(rlist, wlist, xlist[, timeout]) This is a straightforward interface to the Unix select() system call. The first three arguments are sequences of ‘waitable objects’: either integers representing file descriptors or objects with a parameterless method named fileno() returning such an integer: rlist: wait until ready for reading wlist: wait until ready for writing xlist: wait for an “exceptional condition” (see the manual page for what your system considers such a condition)

select.kqueue.fromfd()

kqueue.fromfd(fd) Create a kqueue object from a given file descriptor.

select.kqueue.fileno()

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