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.

◆ receive_credentials() [1/4]

Glib::RefPtr< Credentials > Gio::UnixConnection::receive_credentials ( )

A receive_credentials() convenience overload.

◆ receive_credentials() [2/4]

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

A receive_credentials() convenience overload.

◆ receive_credentials() [3/4]

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.

This method can be expected to be available on the following platforms:

Linux since GLib 2.26
FreeBSD since GLib 2.26
GNU/kFreeBSD since GLib 2.36
Solaris, Illumos and OpenSolaris since GLib 2.40
GNU/Hurd since GLib 2.40

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 nullptr.

Returns: Received credentials on success (free with Glib::object_unref()), nullptr if error is set.

Exceptions

Glib::Error

◆ receive_credentials() [4/4]

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.

This method can be expected to be available on the following platforms:

Linux since GLib 2.26
FreeBSD since GLib 2.26
GNU/kFreeBSD since GLib 2.36

GNU/Hurd since GLib 2.40

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 nullptr.

Returns: Received credentials on success (free with Glib::object_unref()), nullptr if error is set.

Exceptions

Glib::Error

◆ receive_credentials_async() [1/2]

void Gio::UnixConnection::receive_credentials_async	(	const SlotAsyncReady &	slot,
		const Glib::RefPtr< Cancellable > &	cancellable
	)

Asynchronously receive credentials.

For more details, see receive_credentials() which is the synchronous version of this call.

When the operation is finished, slot will be called. You can then call receive_credentials_finish() to get the result of the operation.

Parameters

slot	A SlotAsyncReady to call when the request is satisfied.
cancellable	A Cancellable object.

Since glibmm 2.36:

◆ receive_credentials_finish()

Glib::RefPtr< Credentials > Gio::UnixConnection::receive_credentials_finish ( const Glib::RefPtr< AsyncResult > & result )

Finishes an asynchronous receive credentials operation started with g_unix_connection_receive_credentials_async().

Since glibmm 2.32:

Parameters

result A AsyncResult.

Returns: A Credentials, or nullptr on error. Free the returned object with Glib::object_unref().

Exceptions

Glib::Error

◆ receive_fd() [1/2]

int Gio::UnixConnection::receive_fd ( )

A receive_fd() convenience overload.

◆ receive_fd() [2/2]

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, nullptr to ignore.

Returns: A file descriptor on success, -1 on error.

Exceptions

Glib::Error

◆ send_credentials() [1/2]

bool Gio::UnixConnection::send_credentials ( )

A send_credentials() convenience overload.

◆ send_credentials() [2/2]

bool Gio::UnixConnection::send_credentials ( const Glib::RefPtr< Cancellable > & cancellable )

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

The receiving 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.

This method can be expected to be available on the following platforms:

Linux since GLib 2.26
FreeBSD since GLib 2.26
GNU/kFreeBSD since GLib 2.36
Solaris, Illumos and OpenSolaris since GLib 2.40
GNU/Hurd since GLib 2.40

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

Parameters

cancellable A Cancellable or nullptr.

Returns: true on success, false if error is set.

Exceptions

Glib::Error

◆ send_credentials_async() [1/2]

void Gio::UnixConnection::send_credentials_async	(	const SlotAsyncReady &	slot,
		const Glib::RefPtr< Cancellable > &	cancellable
	)

Asynchronously send credentials.

For more details, see send_credentials() which is the synchronous version of this call.

When the operation is finished, slot will be called. You can then call send_credentials_finish() to get the result of the operation.

Parameters

slot	A SlotAsyncReady to call when the request is satisfied.
cancellable	A Cancellable object.

Since glibmm 2.36:

◆ send_credentials_finish()

bool Gio::UnixConnection::send_credentials_finish ( const Glib::RefPtr< AsyncResult > & result )

Finishes an asynchronous send credentials operation started with g_unix_connection_send_credentials_async().

Since glibmm 2.32:

Parameters

result A AsyncResult.

Returns: true if the operation was successful, otherwise false.

Exceptions

Glib::Error

◆ send_fd() [1/2]

bool Gio::UnixConnection::send_fd ( int fd )

A send_fd() convenience overload.

◆ send_fd() [2/2]

bool Gio::UnixConnection::send_fd	(	int	fd,
		const Glib::RefPtr< Cancellable > &	cancellable
	)

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

The receiving 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, `nullptr` to ignore.

Returns: A true on success, nullptr on error.
