epoll

select

functionDeprecated 3.4Linux >= 2.5.44

epoll(sizehint=-1, flags=0)

Deprecated since 3.4. The flags parameter. select.EPOLL_CLOEXEC is used by default now. Use os.set_inheritable() to make the file descriptor inheritable.

select.epoll(sizehint=-1, flags=0)

Returns an epolling object

sizehint must be a positive integer or -1 for the default size. The
sizehint is used to optimize internal data structures. It doesn't limit
the maximum number of monitored events.

Changed in 3.3, 3.4, 3.15

3.3: Added the flags parameter.
3.4: Support for the with statement was added. The new file descriptor is now non-inheritable.
3.15: When CPython is built, this function may be disabled using --disable-epoll.
