Function Documentation

int dmxCheckSpecialKeys	(	DevicePtr	pDev,
		KeySym	keySym
	)

A pointer to this routine is passed to low-level input drivers so that all special keychecking is unified to this file. This function returns 0 if no special keys have been pressed. If the user has requested termination of the DMX server, -1 is returned. If the user has requested a switch to a VT, then the (1-based) number of that VT is returned.

void dmxEnqueue	(	DevicePtr	pDev,
		int	type,
		int	detail,
		KeySym	keySym,
		XEvent *	e,
		DMXBlockType	block
	)

Enqueue an event from the pDev device with the specified type and detail. If the event is a KeyPress or KeyRelease event, then the keySym is also specified.

FIXME: make the code do what the comment says, or remove this comment. If block is set to DMX_BLOCK, then the SIGIO handler will be blocked around calls to dmxeqEnqueue().

void dmxInvalidateGlobalPosition

(

void

)

Invalidate the global position for dmxCoreMotion.

void dmxMotion	(	DevicePtr	pDev,
		int *	v,
		int	firstAxes,
		int	axesCount,
		DMXMotionType	type,
		DMXBlockType	block
	)

Enqueue a motion event for pDev. The v vector has length axesCount, and contains values for each of the axes, starting at firstAxes.

The type of the motion may be DMX_RELATIVE, DMX_ABSOLUTE, or DMX_ABSOLUTE_CONFINED (in the latter case, the pointer will not be allowed to move outside the global boundaires).

If block is set to DMX_BLOCK, then the SIGIO handler will be blocked around calls to enqueueMotion().
