pymnl Module¶
The NETLINK_* constants in this module help determine which family (a.k.a. sub-protocol or socket bus) to connect with. For example:
>>> import pymnl
>>> import pymnl.nlsocket
>>> sock = pymnl.nlsocket.Socket(pymnl.NETLINK_ROUTE)
>>> sock.bind()
will bind sock to the kernel's routing information so that
queries can be run and changes can be requested.
