Network interfaces discovery — Utility functions to discover local network interfaces

Stability Level

Stable, unless otherwise indicated

Functions

gchar *	nice_interfaces_get_ip_for_interface ()
GList *	nice_interfaces_get_local_interfaces ()
GList *	nice_interfaces_get_local_ips ()

Includes

#include <interfaces.h>

Description

These utility functions allow the discovery of local network interfaces in a portable manner, they also allow finding the local ip addresses or the address allocated to a network interface.

Functions

nice_interfaces_get_ip_for_interface ()

gchar *
nice_interfaces_get_ip_for_interface (gchar *interface_name);

Retrieves the IP address of an interface by its name. If this fails, NULL is returned.

Parameters

interface_name

name of local interface

Returns

a newly-allocated string with the IP address.

nice_interfaces_get_local_interfaces ()

GList *
nice_interfaces_get_local_interfaces (void);

Get the list of local interfaces

Returns

a newly-allocated GList of strings. The caller must free it.

[element-type utf8][transfer full]

nice_interfaces_get_local_ips ()

GList *
nice_interfaces_get_local_ips (gboolean include_loopback);

Get a list of local ipv4 interface addresses

Parameters

include_loopback

Include any loopback devices

Returns

a newly-allocated GList of strings. The caller must free it.
