## Detailed Description

Abstract base class representing endpoints for socket communication.

Since glibmm 2.24:

## Constructor & Destructor Documentation

Gio::SocketAddress::SocketAddress | ( | SocketAddress&& | src | ) |

noexcept

Gio::SocketAddress::~SocketAddress | ( |  | ) |

override noexcept

## Member Function Documentation

static Glib::RefPtr<SocketAddress> Gio::SocketAddress::create | ( | gpointer | native,
|  | gsize | len
| ) |  |

static

Creates a SocketAddress subclass corresponding to the native struct sockaddr native.

Since glibmm 2.22:

Parameters

  native | A pointer to a struct sockaddr.
  len | The size of the memory location pointed to by native.

Returns
  A new SocketAddress if native could successfully be converted, otherwise `nullptr`.

SocketFamily Gio::SocketAddress::get_family | ( |  | ) | const

Gets the socket family type of address.

Since glibmm 2.22:

Returns
  The socket family type of address.

gssize Gio::SocketAddress::get_native_size | ( |  | ) | const

Gets the size of address's native struct sockaddr.

You can use this to allocate memory to pass to g_socket_address_to_native().

Since glibmm 2.22:

Returns
  The size of the native struct sockaddr that address represents.

static GType Gio::SocketAddress::get_type | ( |  | ) |

static

Get the GType for this class, for use with the underlying GObject type system.

GSocketAddress* Gio::SocketAddress::gobj | ( |  | ) |

inline

Provides access to the underlying C GObject.

const GSocketAddress* Gio::SocketAddress::gobj | ( |  | ) | const

inline

Provides access to the underlying C GObject.

GSocketAddress* Gio::SocketAddress::gobj_copy | ( |  | ) |

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

SocketAddress& Gio::SocketAddress::operator= | ( | SocketAddress&& | src | ) |

noexcept

Glib::PropertyProxy_ReadOnly< Glib::RefPtr<SocketFamily> > Gio::SocketAddress::property_family | ( |  | ) | const

The family of the socket address.

Default value: SOCKET_FAMILY_INVALID

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

bool Gio::SocketAddress::to_native | ( | gpointer | dest,
|  | gsize | destlen
| ) |  |

Converts a SocketAddress to a native struct sockaddr, which can be passed to low-level functions like connect() or bind().

If not enough space is available, a IO_ERROR_NO_SPACE error is returned. If the address type is not known on the system then a IO_ERROR_NOT_SUPPORTED error is returned.

Since glibmm 2.22:

Parameters

  dest | A pointer to a memory location that will contain the native struct sockaddr.
  destlen | The size of dest. Must be at least as large as g_socket_address_get_native_size().

Returns
  `true` if dest was filled in, `false` on error.

Exceptions

  Glib::Error |

## Friends And Related Function Documentation

Glib::RefPtr< Gio::SocketAddress > wrap | ( | GSocketAddress * | 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.
