UnixFDMessage

open class UnixFDMessage(pointer: <Error class: unknown class><<Error class: unknown class>>) : SocketControlMessage

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_FAMILY_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.

Functions

Link copied to clipboard
open fun appendFd(fd: Int): <Error class: unknown class><Boolean>

Adds a file descriptor to @message.

Link copied to clipboard
open fun getFdList(): UnixFDList

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.

Link copied to clipboard
open fun getLevel(): Int

Returns the "level" (i.e. the originating protocol) of the control message. This is often SOL_SOCKET.

Link copied to clipboard
open fun getMsgType(): Int

Returns the protocol specific type of the control message. For instance, for UNIX fd passing this would be SCM_RIGHTS.

Link copied to clipboard
open fun getSize(): <Error class: unknown class>

Returns the space required for the control message, not including headers or alignment.
