PointerInterface
public class UnixFDMessage extends SocketControlMessage
This [class@Gio.SocketControlMessage] contains a [class@Gio.UnixFDList].
It may be sent using [method@Gio.Socket.send_message] and received using
[method@Gio.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 [method@Gio.UnixConnection.send_fd] and
[method@Gio.UnixConnection.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 or the `GioUnix-2.0` GIR namespace when using it.

  • Konstruktordetails

    • UnixFDMessage

      public UnixFDMessage(PointerContainer pointer)

    • UnixFDMessage

      public UnixFDMessage()
      Creates a new #GUnixFDMessage containing an empty file descriptor
      list.

  • Methodendetails

    • getClassHandler

      public static ClassHandler getClassHandler()

    • newWithFdListUnixFDMessage

      public static UnixFDMessage newWithFdListUnixFDMessage(@Nonnull UnixFDList fd_list)
      Creates a new #GUnixFDMessage containing @list.
      Parameter:
      fd_list - a #GUnixFDList
      Gibt zurück:
      a new #GUnixFDMessage

    • appendFd

      public boolean appendFd(int fd) throws AllocationError
      Adds a file descriptor to @message.

      The file descriptor is duplicated using dup(). You keep your copy
      of the descriptor and the copy contained in @message will be closed
      when @message is finalized.

      A possible cause of failure is exceeding the per-process or
      system-wide file descriptor limit.
      Parameter:
      fd - a valid open file descriptor
      Gibt zurück:
      %TRUE in case of success, else %FALSE (and @error is set)
      Löst aus:
      AllocationError

    • getFdList

      public 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.
      Gibt zurück:
      the #GUnixFDList from @message

    • stealFds

      public Int stealFds(@Nullable Int length)
      Returns the array of file descriptors that is contained in this
      object.

      After this call, the descriptors are no longer contained in
      @message. Further calls will return an empty list (unless more
      descriptors have been added).

      The return result of this function must be freed with g_free().
      The caller is also responsible for closing all of the file
      descriptors.

      If @length is non-%NULL then it is set to the number of file
      descriptors in the returned array. The returned array is also
      terminated with -1.

      This function never returns %NULL. In case there are no file
      descriptors contained in @message, an empty array is returned.
      Parameter:
      length - pointer to the length of the returned array, or %NULL
      Gibt zurück:
      an array of file descriptors
