 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.

Member Function Documentation

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

Provides access to the underlying C GObject.

Reimplemented from Gio::SocketConnection.

const GUnixConnection* Gio::UnixConnection::gobj ( ) const [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.

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:
cancellableA Cancellable or 0.
Returns:
Received credentials on success (free with Glib::object_unref()), 0 if error is set.

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:
cancellableA Cancellable or 0.
Returns:
Received credentials on success (free with Glib::object_unref()), 0 if error is set.

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:
cancellableOptional Cancellable object, 0 to ignore.
Returns:
A file descriptor on success, -1 on error.

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.

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

Since glibmm 2.26:
Parameters:
cancellableA 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 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:
fdA file descriptor.
cancellableOptional Cancellable object, 0 to ignore.
Returns:
A true on success, 0 on error.
