Removed Functions
The following R3 functions are not in R4:

XtSetAsyncEventHandler XtMakeToolkitAsync
XtGetResources                  XtInitialize Changes to Function Prototypes
The XtEventHandler function prototype has changed, now having 4 arguments instead of 3:

XtEventHandler typedef void (∗XtEventHandler)()
 Widget    widget
 XtPointer closure     /∗  XtPointer instead of caddr_t ∗/
 XEvent∗   event
 Boolean∗  continue_to_dispatch /∗ New argument ∗/ The following R3 function prototypes have gone away:

XtAllEventsXtAsyncHandler

The following R4 function prototypes are new:

XtActionHookProc XtCancelConvertSelectionProc
XtConvertArgProc XtConvertSelectionIncrProc
XtConvertSelectionProc XtLoseSelectionIncrProc
XtLoseSelectionProc XtSelectionCallbackProc
XtSelectionDoneIncrProc XtSelectionDoneProc
XtTypeConverter New Types
The new type XtPointer replaces caddr_t in the following functions:

XtAddCallback XtAddEventHandler
XtAddRawEventHandler XtCallCallbacks
XtCallbackExclusive XtCallbackNone
XtCallbackNonexclusive XtCallbackPopdown
XtCallbackProc XtCallbackRec
XtEventHandler XtGetSubresources
XtGetSubvalues XtInputCallbackProc
XtRemoveCallback         XtRemoveEventHandler
XtRemoveRawEventHandler XtResource
XtSetSubvalues XtTimerCallbackProc
XtWorkProc
