All errors raise exceptions. The normal exceptions for invalid argument types

Non-blocking mode is supported through :meth:`~socket.setblocking`. A
generalization of this based on timeouts is supported through
Unix manual page :manpage:`inet(3)` for details.
If the IPv4 address string passed to this function is invalid,

the underlying C implementation of :c:func:`inet_aton`.
:func:`inet_aton` does not support IPv6, and :func:`inet_pton` should be used
argument.
If the byte sequence passed to this function is not exactly 4 bytes in
- length, :exc:`socket.error` will be raised. :func:`inet_ntoa` does not

support IPv6, and :func:`inet_ntop` should be used instead for IPv4/v6 dual
stack support.
Supported values for *address_family* are currently :const:`AF_INET` and
:const:`AF_INET6`. If the IP address string *ip_string* is invalid,
- :exc:`socket.error` will be raised. Note that exactly what is valid depends on

Supported values for *address_family* are currently :const:`AF_INET` and
:const:`AF_INET6`. If the string *packed_ip* is not the correct length for the
specified address family, :exc:`ValueError` will be raised. A
- :exc:`socket.error` is raised for errors from the call to :func:`inet_ntop`.
+ :exc:`OSError` is raised for errors from the call to :func:`inet_ntop`.

.. function:: sethostname(name)
Set the machine's hostname to *name*. This will raise a

Running an example several times with too small delay between executions, could
lead to this error::
- socket.error: [Errno 98] Address already in use
+ OSError: [Errno 98] Address already in use
This is because the previous execution has left the socket in a ``TIME_WAIT``
state, and can't be immediately reused.
