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 a non-motion 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.

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 dmxeqEnqueue().
