IOFuncs
===================================================================

.. currentmodule:: gi.repository.GLib





.. class:: IOFuncs(*args, **kwargs)
   :no-contents-entry:






A table of functions used to handle different types of :obj:`~gi.repository.GLib.IOChannel`
in a generic way.












Fields
------

.. rst-class:: interim-class

.. class:: IOFuncs
   :no-index:
   

   .. attribute:: io_close

      Closes the channel.  This is called from
                 :func:`~gi.repository.GLib.IOChannel.close` after flushing the buffers.






   .. attribute:: io_create_watch

      Creates a watch on the channel.  This call
                        corresponds directly to :func:`~gi.repository.GLib.io_create_watch`.






   .. attribute:: io_free

      Called from :func:`~gi.repository.GLib.IOChannel.unref` when the channel needs to
                be freed.  This function must free the memory associated
                with the channel, including freeing the :obj:`~gi.repository.GLib.IOChannel`
                structure itself.  The channel buffers have been flushed
                and possibly ``io_close`` has been called by the time this
                function is called.






   .. attribute:: io_get_flags

      Gets the :obj:`~gi.repository.GLib.IOFlags` for the channel.  This function
                     need only return the :const:`~gi.repository.GLib.IOFlags.APPEND` and
                     :const:`~gi.repository.GLib.IOFlags.NONBLOCK` flags; :func:`~gi.repository.GLib.IOChannel.get_flags`
                     automatically adds the others as appropriate.






   .. attribute:: io_read

      Reads raw bytes from the channel.  This is called from
                various functions such as :func:`~gi.repository.GLib.IOChannel.read_chars` to
                read raw bytes from the channel.  Encoding and buffering
                issues are dealt with at a higher level.






   .. attribute:: io_seek

      Seeks the channel.  This is called from
                :func:`~gi.repository.GLib.IOChannel.seek` on channels that support it.






   .. attribute:: io_set_flags

      Sets the :obj:`~gi.repository.GLib.IOFlags` on the channel.  This is called
                     from :func:`~gi.repository.GLib.IOChannel.set_flags` with all flags except
                     for :const:`~gi.repository.GLib.IOFlags.APPEND` and :const:`~gi.repository.GLib.IOFlags.NONBLOCK` masked
                     out.






   .. attribute:: io_write

      Writes raw bytes to the channel.  This is called from
                 various functions such as :func:`~gi.repository.GLib.IOChannel.write_chars` to
                 write raw bytes to the channel.  Encoding and buffering
                 issues are dealt with at a higher level.
