XkbFreeServerMap(3)		 XKB FUNCTIONS		   XkbFreeServerMap(3)

       XkbFreeServerMap	 -  Free memory used by the server member of an XkbDe‐
       scRec structure

       void  XkbFreeServerMap  (XkbDescPtr  xkb,  unsigned  int	 which,	  Bool

       - xkb  keyboard description containing server map to free

       - which
	      mask identifying components of map to free

       - free_all
	      True => free all server map components and server itself

       The  XkbFreeServerMap function frees the specified components of server
       map in the XkbDescRec structure specified by the xkb parameter and sets
       the corresponding structure component values to NULL. The which parame‐
       ter specifies a combination of the server map masks and	is  a  bitwise
       inclusive OR of the masks listed in Table 1. If free_all is True, which
       is ignored and XkbFreeServerMap frees every non-NULL  structure	compo‐
       nent  in the server map, frees the XkbServerMapRec structure referenced
       by the server member of the xkb parameter, and sets the	server	member
       to NULL.

			 Table 1 XkbAllocServerMap Masks
       Mask			   Effect
       XkbExplicitComponentsMask   The min_key_code and max_key_code fields
				   of the xkb parameter are used  to  allo‐
				   cate	 the  explicit	field of the server

       XkbKeyActionsMask	   The min_key_code and max_key_code fields
				   of  the  xkb parameter are used to allo‐
				   cate the key_acts field  of	the  server
				   map. The count_acts parameter is used to
				   allocate the acts field  of	the  server

       XkbKeyBehaviorsMask	   The min_key_code and max_key_code fields
				   of the xkb parameter are used  to  allo‐
				   cate	 the  behaviors field of the server

       XkbVirtualModMapMask	   The min_key_code and max_key_code fields
				   of  the  xkb parameter are used to allo‐
				   cate the vmodmap  field  of	the  server

       The  complete description of an Xkb keyboard is given by an XkbDescRec.
       The component structures in the XkbDescRec represent the major Xkb com‐

       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.

       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 2.

	       Table 2 Mask Bits for XkbDescRec
       Mask Bit		      XkbDescRec Field	 Value
       XkbControlsMask	      ctrls		 (1L<<0)
       XkbServerMapMask	      server		 (1L<<1)
       XkbIClientMapMask      map		 (1L<<2)
       XkbIndicatorMapMask    indicators	 (1L<<3)
       XkbNamesMask	      names		 (1L<<4)
       XkbCompatMapMask	      compat		 (1L<<5)
       XkbGeometryMask	      geom		 (1L<<6)
       XkbAllComponentsMask   All Fields	 (0x7f)

       The  Xkb server map contains the information the server needs to inter‐
       pret key events and is of type XkbServerMapRec:

       #define XkbNumVirtualMods	  16

       typedef struct {			   /∗ Server Map */
	   unsigned short    num_acts;	   /∗ # of occupied entries in acts */
	   unsigned short    size_acts;	   /∗ # of entries in acts */
	   XkbAction *	     acts;	   /∗ linear 2d tables of key actions, 1 per keycode */
	   XkbBehavior *     behaviors;	   /∗ key behaviors,1 per keycode */
	   unsigned short *  key_acts;	   /∗ index into acts, 1 per keycode */
	   unsigned char *   explicit;	   /∗ explicit overrides of core remapping, 1 per key */
	   unsigned char     vmods[XkbNumVirtualMods]; /∗ real mods bound to virtual mods */
	   unsigned short *  vmodmap;	   /∗ virtual mods bound to key, 1 per keycode*/
       } XkbServerMapRec, *XkbServerMapPtr;
