Add a network route for DESTINATION (a socket address as returned by 'make-socket-address') that goes through GATEWAY (a socket address). For instance, the call:

(add-network-route/gateway sock (make-socket-address AF_INET (inet-pton AF_INET "192.168.0.1") 0))

is equivalent to this 'net-tools' command:

route add -net default gw 192.168.0.1

because the default value of DESTINATION is "0.0.0.0".

Return a number that is the bit-wise or of 'IFF*' flags for network interface NAME.

Set extended attribute KEY to VALUE on FILE.

Return the list of entries read from the user accounting database.

Delete the network route for DESTINATION. For instance, the call:

(delete-network-route sock (make-socket-address AF_INET INADDR_ANY 0))

is equivalent to the 'net-tools' command:

route del -net default
