-/**
- * clutter_x11_enable_xinput:
- *
- * Enables the use of the XInput extension if present on connected
- * XServer and support built into Clutter. XInput allows for multiple
- * pointing devices to be used.
- *
- * This function must be called before clutter_init().
- *
- * Since XInput might not be supported by the X server, you might
- * want to use clutter_x11_has_xinput() to see if support was enabled.
- *
- * Since: 0.8
- *
- * Deprecated: 1.14: This function does not do anything; XInput support
- *   is enabled by default in Clutter. Use the CLUTTER_DISABLE_XINPUT
- *   environment variable to disable XInput support and use Xlib core
- *   events instead.
