## Detailed Description

A SocketConnectable for resolving hostnames.

NetworkAddress provides an easy way to resolve a hostname and then attempt to connect to that host, handling the possibility of multiple IP addresses and multiple address families.

Since glibmm 2.24:

## Constructor & Destructor Documentation

virtual Gio::NetworkAddress::~NetworkAddress | ( |  | ) | `[virtual]`

## Member Function Documentation

static Glib::RefPtr<NetworkAddress> Gio::NetworkAddress::create | ( | const std::string & | hostname,
|  | guint16 | port |
| ) |  |  | `[static]`

std::string Gio::NetworkAddress::get_hostname | ( |  | ) | const

Gets addr's hostname.

This might be either UTF-8 or ASCII-encoded, depending on what addr was created with.

Since glibmm 2.22:

Returns:
  addr's hostname.

guint16 Gio::NetworkAddress::get_port | ( |  | ) | const

Gets addr's port number.

Since glibmm 2.22:

Returns:
  addr's port (which may be 0).

const GNetworkAddress* Gio::NetworkAddress::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GObject.

Reimplemented from Gio::SocketConnectable.

GNetworkAddress* Gio::NetworkAddress::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C GObject.

Reimplemented from Gio::SocketConnectable.

GNetworkAddress* Gio::NetworkAddress::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

static Glib::RefPtr<NetworkAddress> Gio::NetworkAddress::parse | ( | const std::string & | host_and_port,
|  | guint16 | default_port |
| ) |  |  | `[static]`

Glib::PropertyProxy_ReadOnly<std::string> Gio::NetworkAddress::property_hostname | ( |  | ) | const

Hostname to resolve.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly<guint> Gio::NetworkAddress::property_port | ( |  | ) | const

Network port.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

## Friends And Related Function Documentation

Glib::RefPtr< Gio::NetworkAddress > wrap | ( | GNetworkAddress * | object,
|  | bool | take_copy = `false` |
| ) |  |  | `[related]`

A Glib::wrap() method for this object.

Parameters:

  | object | The C instance.
  | take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:
  A C++ instance that wraps this C instance.
