## Detailed Description

UnixCredentialsMessage - A SocketControlMessage containing credentials.

This SocketControlMessage contains a Credentials instance. It may be sent using Gio::Socket::send() and received using Gio::Socket::receive() over UNIX sockets (ie: sockets in the Gio::SOCKET_FAMILY_UNIX family).

For an easier way to send and receive credentials over stream-oriented UNIX sockets, see Gio::UnixConnection::send_credentials() and Gio::UnixConnection::receive_credentials(). To receive credentials of a foreign process connected to a socket, use Gio::Socket::get_credentials().

Since glibmm 2.28:

## Member Function Documentation

static Glib::RefPtr<UnixCredentialsMessage> Gio::UnixCredentialsMessage::create | ( |  | ) | `[static]`

Creates a new UnixCredentialsMessage with credentials matching the current processes.

Since glibmm 2.26:

Returns:
  A new UnixCredentialsMessage.

static Glib::RefPtr<UnixCredentialsMessage> Gio::UnixCredentialsMessage::create | ( | const Glib::RefPtr< Credentials >& | credentials | ) | `[static]`

Creates a new UnixCredentialsMessage holding credentials.

Since glibmm 2.26:

Parameters:

  credentials | A Credentials object.

Returns:
  A new UnixCredentialsMessage.

Glib::RefPtr<Credentials> Gio::UnixCredentialsMessage::get_credentials | ( |  | ) |

Gets the credentials stored in message.

Since glibmm 2.26:

Returns:
  A Credentials instance. Do not free, it is owned by message.

Glib::RefPtr<const Credentials> Gio::UnixCredentialsMessage::get_credentials | ( |  | ) | const

Gets the credentials stored in message.

Since glibmm 2.26:

Returns:
  A Credentials instance. Do not free, it is owned by message.

const GUnixCredentialsMessage* Gio::UnixCredentialsMessage::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GObject.

Reimplemented from Gio::SocketControlMessage.

GUnixCredentialsMessage* Gio::UnixCredentialsMessage::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C GObject.

Reimplemented from Gio::SocketControlMessage.

GUnixCredentialsMessage* Gio::UnixCredentialsMessage::gobj_copy | ( |  | ) |

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

Reimplemented from Gio::SocketControlMessage.

static bool Gio::UnixCredentialsMessage::is_supported | ( |  | ) | `[static]`

Checks if passing a Credential on a Socket is supported on this platform.

Since glibmm 2.26:

Returns:
  `true` if supported, `false` otherwise.

Glib::PropertyProxy_ReadOnly< Glib::RefPtr<Credentials> > Gio::UnixCredentialsMessage::property_credentials | ( |  | ) | const

The credentials stored in the message.

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::UnixCredentialsMessage > wrap | ( | GUnixCredentialsMessage * | 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.
