Description

GInetAddress represents an IPv4 or IPv6 internet address. Use g_resolver_lookup_by_name() or g_resolver_lookup_by_name_async() to look up the GInetAddress for a hostname. Use g_resolver_lookup_by_address() or g_resolver_lookup_by_address_async() to look up the hostname for a GInetAddress.

To actually connect to a remote host, you will need a GInetSocketAddress (which includes a GInetAddress as well as a port number).

Functions

g_inet_address_new_from_string ()

GInetAddress *
g_inet_address_new_from_string (const gchar *string);

Parses string as an IP address and creates a new GInetAddress.

Parameters

string

a string representation of an IP address

  

Returns

a new GInetAddress corresponding to string , or NULL if string could not be parsed. Free the returned object with g_object_unref().

Since: 2.22

g_inet_address_new_from_bytes ()

GInetAddress *
g_inet_address_new_from_bytes (const guint8 *bytes,
                               GSocketFamily family);

Creates a new GInetAddress from the given family and bytes . bytes should be 4 bytes for G_SOCKET_FAMILY_IPV4 and 16 bytes for G_SOCKET_FAMILY_IPV6.

Parameters

bytes

raw address data.

[array][element-type guint8]

family

the address family of bytes

 

Returns

a new GInetAddress corresponding to family and bytes . Free the returned object with g_object_unref().

Since: 2.22

g_inet_address_new_any ()

GInetAddress *
g_inet_address_new_any (GSocketFamily family);

Creates a GInetAddress for the "any" address (unassigned/"don't care") for family .

Parameters

family

the address family

  

Returns

a new GInetAddress corresponding to the "any" address for family . Free the returned object with g_object_unref().

Since: 2.22

g_inet_address_new_loopback ()

Checks if two GInetAddress instances are equal, e.g. the same address.

Parameters
