Detailed Description

This file provides access to:

• global variables available to all hw/dmx routines, and
• enumerations and typedefs needed by input routines in hw/dmx (and hw/dmx/input).

The goal is that no files in hw/dmx should include header files from hw/dmx/input – the interface defined here should be the only interface exported to the hw/dmx layer.

input/dmxinputinit.c.

Macro Definition Documentation

#define DMX_MAX_SIGIO_FDS   4

Maximum number of file descriptors for SIGIO handling

Referenced by dmxSigioRegister().

Typedef Documentation

typedef struct _DMXLocalInputInfo* DMXLocalInputInfoPtr

An opaque structure that is only exposed in the dmx/input layer.

typedef void(* ProcessInputEventsProc)(struct _DMXInputInfo *)

typedef void(* UpdateWindowInfoProc)(struct _DMXInputInfo *, DMXUpdateType, WindowPtr)

Enumeration Type Documentation

enum DMXBlockType

Enumerator
DMX_NO_BLOCK
DMX_BLOCK

enum dmxSigioState

State of the SIGIO engine

Enumerator
DMX_NOSIGIO	Device does not use SIGIO at all.
DMX_USESIGIO	Device can use SIGIO, but is not (e.g., because the VT is switch away).
DMX_ACTIVESIGIO	Device is currently using SIGIO.

enum DMXUpdateType

Reason why window layout was updated.

Enumerator
DMX_UPDATE_REALIZE	Window realized
DMX_UPDATE_UNREALIZE	Window unrealized
DMX_UPDATE_RESTACK	Stacking order changed
DMX_UPDATE_COPY	Window copied
DMX_UPDATE_RESIZE	Window resized
DMX_UPDATE_REPARENT	Window reparented
