| 37 | * This file provides access to: | |
| 38 | * - global variables available to all hw/dmx routines, and | |
| 39 | * - enumerations and typedefs needed by input routines in hw/dmx (and | |
| 40 | * hw/dmx/input). | |
| 41 | * | |
| 42 | * The goal is that no files in hw/dmx should include header files from | |
| 43 | * hw/dmx/input -- the interface defined here should be the only | |
| 44 | * interface exported to the hw/dmx layer. \see input/dmxinputinit.c. | |
