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).

Details

GInetAddress

typedef struct _GInetAddress GInetAddress;

An IPv4 or IPv6 internet address.

g_inet_address_new_from_string ()

GInetAddress *         g_inet_address_new_from_string   (const gchar *string);
