virtual ~UnixConnection ()
GUnixConnection* gobj ()
 Provides access to the underlying C GObject.
const GUnixConnection* gobj () const
 Provides access to the underlying C GObject.

 Passes a file descriptor to the recieving side of the connection.
int receive_fd (const Glib::RefPtr< Cancellable >& cancellable)
 Receives a file descriptor from the sending end of the connection.
Glib::RefPtr< Credentialsreceive_credentials (const Glib::RefPtr< Cancellable >& cancellable)
 Receives credentials from the sending end of the connection.
Glib::RefPtr< const Credentialsreceive_credentials (const Glib::RefPtr< Cancellable >& cancellable) const
 Receives credentials from the sending end of the connection.
bool send_credentials (const Glib::RefPtr< Cancellable >& cancellable)

Glib::RefPtr< Gio::UnixConnectionwrap (GUnixConnection* object, bool take_copy=false)
 A Glib::wrap() method for this object.

Detailed Description

A Unix domain SocketConnection.

This is the subclass of SocketConnection that is created for UNIX domain sockets.

It contains functions to do some of the unix socket specific functionallity like passing file descriptors.

Since glibmm 2.24:

Member Function Documentation

const GUnixConnection* Gio::UnixConnection::gobj (  )  const [inline]

Provides access to the underlying C GObject.

Reimplemented from Gio::SocketConnection.

GUnixConnection* Gio::UnixConnection::gobj (  )  [inline]

Provides access to the underlying C GObject.

Reimplemented from Gio::SocketConnection.

GUnixConnection* Gio::UnixConnection::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::SocketConnection.

Glib::RefPtr<const Credentials> Gio::UnixConnection::receive_credentials ( const Glib::RefPtr< Cancellable >&  cancellable  )  const

Receives credentials from the sending end of the connection.

The sending end has to call g_unix_connection_send_credentials() (or similar) for this to work.

As well as reading the credentials this also reads (and discards) a single byte from the stream, as this is required for credentials passing to work on some implementations.

Other ways to exchange credentials with a foreign peer includes the UnixCredentialsMessage type and g_socket_get_credentials() function.

Since glibmm 2.26:
Parameters:
cancellable A Cancellable or 0.
Returns:
Received credentials on success (free with Glib::object_unref()), 0 if error is set.
Glib::RefPtr<Credentials> Gio::UnixConnection::receive_credentials ( const Glib::RefPtr< Cancellable >&  cancellable  ) 

Receives credentials from the sending end of the connection.

The sending end has to call g_unix_connection_send_credentials() (or similar) for this to work.

As well as reading the credentials this also reads (and discards) a single byte from the stream, as this is required for credentials passing to work on some implementations.

Other ways to exchange credentials with a foreign peer includes the UnixCredentialsMessage type and g_socket_get_credentials() function.

Since glibmm 2.26:
Parameters:
cancellable A Cancellable or 0.
Returns:
Received credentials on success (free with Glib::object_unref()), 0 if error is set.
int Gio::UnixConnection::receive_fd ( const Glib::RefPtr< Cancellable >&  cancellable  ) 

Receives a file descriptor from the sending end of the connection.

The sending end has to call g_unix_connection_send_fd() for this to work.

As well as reading the fd this also reads a single byte from the stream, as this is required for fd passing to work on some implementations.

Since glibmm 2.22:
Parameters:
cancellable Optional Cancellable object, 0 to ignore.
Returns:
A file descriptor on success, -1 on error.
bool Gio::UnixConnection::send_credentials ( const Glib::RefPtr< Cancellable >&  cancellable  ) 

Passes the credentials of the current user the receiving side of the connection.

The recieving end has to call g_unix_connection_receive_credentials() (or similar) to accept the credentials.

As well as sending the credentials this also writes a single NUL byte to the stream, as this is required for credentials passing to work on some implementations.

Other ways to exchange credentials with a foreign peer includes the UnixCredentialsMessage type and g_socket_get_credentials() function.

Note that this function only works on Linux, currently.

Since glibmm 2.26:
Parameters:
cancellable A Cancellable or 0.
Returns:
true on success, false if error is set.
bool Gio::UnixConnection::send_fd ( int  fd,
const Glib::RefPtr< Cancellable >&  cancellable 
)

Passes a file descriptor to the recieving side of the connection.

The recieving end has to call g_unix_connection_receive_fd() to accept the file descriptor.

As well as sending the fd this also writes a single byte to the stream, as this is required for fd passing to work on some implementations.

Since glibmm 2.22:
Parameters:
fd A file descriptor.
cancellable Optional Cancellable object, 0 to ignore.
Returns:
A true on success, 0 on error.
