XkbFreeCompatMap(3)			  XKB FUNCTIONS 		      XkbFreeCompatMap(3)

       XkbFreeCompatMap - Free an entire compatibility map or selected portions of one

       void XkbFreeCompatMap ( xkb, which, free_map )
	     XkbDescPtr xkb;
	     unsigned int which;
	     Bool free_map;

       - xkb  Xkb description in which to free compatibility map

       - which
	      mask of compatibility map components to free

       - free_map
	      True => free XkbCompatMap structure itself

       which specifies the compatibility map components to be freed (see XkbGetCompatMap).  which
       is an inclusive OR of the bits shown in Table 1.

		 Table 1 Compatibility Map Component Masks
       Mask		    Value    Affecting
       XkbSymInterpMask     (1<<0)   Symbol interpretations
       XkbGroupCompatMask   (1<<1)   Group maps
       XkbAllCompatMask     (0x3)    All compatibility map components

       free_map indicates whether the XkbCompatMap structure itself should be freed. If  free_map
       is  True,  which  is ignored, all non-NULL compatibility map components are freed, and the
       compat field in the XkbDescRec referenced by xkb is set to NULL.

	   typedef struct _XkbCompatMapRec {
	       XkbSymInterpretPtr    sym_interpret;	       /* symbol based key semantics*/
	       XkbModsRec	     groups[XkbNumKbdGroups];  /* group => modifier map */
	       unsigned short	     num_si;		       /* # structures used in sym_interpret */
	       unsigned short	     size_si;		       /* # structures allocated in sym_interpret */
	   } XkbCompatMapRec, *XkbCompatMapPtr;

       The complete description of an Xkb keyboard is  given  by  an  XkbDescRec.  The	component
       structures in the XkbDescRec represent the major Xkb components outlined in Figure 1.1.

       typedef struct {
	  struct _XDisplay * display;	   /* connection to X server */
	  unsigned short     flags;	   /* private to Xkb, do not modify */
	  unsigned short     device_spec;  /* device of interest */
	  KeyCode	     min_key_code; /* minimum keycode for device */
	  KeyCode	     max_key_code; /* maximum keycode for device */
	  XkbControlsPtr     ctrls;	   /* controls */
	  XkbServerMapPtr    server;	   /* server keymap */
	  XkbClientMapPtr    map;	   /* client keymap */
	  XkbIndicatorPtr    indicators;   /* indicator map */
	  XkbNamesPtr	     names;	   /* names for all components */
	  XkbCompatMapPtr    compat;	   /* compatibility map */
	  XkbGeometryPtr     geom;	   /* physical geometry of keyboard */
       } XkbDescRec, *XkbDescPtr;

       The  display  field  points  to	an X display structure. The flags field is private to the
       library: modifying flags may yield unpredictable results. The device_spec field	specifies
       the device identifier of the keyboard input device, or XkbUseCoreKeyboard, which specifies
       the core keyboard device. The min_key_code and max_key_code fields specify the  least  and
       greatest keycode that can be returned by the keyboard.  The other fields specify structure
       components of the keyboard description and are described in detail in  other  sections  of
       this  document.	Table  2 identifies the subsequent sections of this document that discuss
       the individual components of the XkbDescRec.

       Each structure component has a corresponding mask bit that is used in  function	calls  to
       indicate that the structure should be manipulated in some manner, such as allocating it or
       freeing it. These masks and their relationships to the fields in the XkbDescRec are  shown
       in Table 3.
