Gets the current flags for a #GIOChannel, including read-only
flags such as %G_IO_FLAG_IS_READABLE.
The values of the flags %G_IO_FLAG_IS_READABLE and %G_IO_FLAG_IS_WRITABLE
are cached for internal use by the channel when it is created.
If they should change at some later point (e.g. partial shutdown
of a socket with the UNIX shutdown() function), the user
should immediately call g_io_channel_get_flags() to update
the internal values of these flags.
