UnixFDMessage

This #GSocketControlMessage contains a #GUnixFDList. It may be sent using g_socket_send_message() and received using g_socket_receive_message() over UNIX sockets (ie: sockets in the %G_SOCKET_ADDRESS_UNIX family). The file descriptors are copied between processes by the kernel.

For an easier way to send and receive file descriptors over stream-oriented UNIX sockets, see g_unix_connection_send_fd() and g_unix_connection_receive_fd().

Note that <gio/gunixfdmessage.h> belongs to the UNIX-specific GIO interfaces, thus you have to use the gio-unix-2.0.pc pkg-config file when using it.

Constructors

this this(GUnixFDMessage* gUnixFDMessage, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(): Creates a new #GUnixFDMessage containing an empty file descriptor list.
this this(UnixFDList fdList): Creates a new #GUnixFDMessage containing @list.

Members

Functions

appendFd bool appendFd(int fd): Adds a file descriptor to @message.
getFdList UnixFDList getFdList(): Gets the #GUnixFDList contained in @message. This function does not return a reference to the caller, but the returned list is valid for the lifetime of @message.
getStruct void* getStruct(): the main Gtk struct as a void*
getUnixFDMessageStruct GUnixFDMessage* getUnixFDMessageStruct(bool transferOwnership): Get the main Gtk struct
setStruct void setStruct(GObject* obj): Undocumented in source. Be warned that the author may not have intended to support it.
stealFds int[] stealFds(): Returns the array of file descriptors that is contained in this object.

From SocketControlMessage

gSocketControlMessage GSocketControlMessage* gSocketControlMessage;: the main Gtk struct
getSocketControlMessageStruct GSocketControlMessage* getSocketControlMessageStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
setStruct void setStruct(GObject* obj): Undocumented in source. Be warned that the author may not have intended to support it.
getType GType getType()
deserialize SocketControlMessage deserialize(int level, int type, ubyte[] data): Tries to deserialize a socket control message of a given @level and @type. This will ask all known (to GType) subclasses of #GSocketControlMessage if they can understand this kind of message and if so deserialize it into a #GSocketControlMessage.
getLevel int getLevel(): Returns the "level" (i.e. the originating protocol) of the control message. This is often SOL_SOCKET.
getMsgType int getMsgType(): Returns the protocol specific type of the control message. For instance, for UNIX fd passing this would be SCM_RIGHTS.
getSize size_t getSize(): Returns the space required for the control message, not including headers or alignment.
serialize void serialize(void* data): Converts the data in the message to bytes placed in the message.
