XkbFreeServerMap(3)              XKB FUNCTIONS             XkbFreeServerMap(3)



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

SYNOPSIS
       void XkbFreeServerMap ( xkb, which, free_all )
             XkbDescPtr xkb;
             unsigned int which;
             Bool free_all;

ARGUMENTS
       - 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

DESCRIPTION
       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.

       server map.  T}

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

       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.

       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;
