XkbAllocCompatMap(3)             XKB FUNCTIONS             XkbAllocCompatMap(3)

NAME
       XkbAllocCompatMap  -  Allocate a new compatibility map if you do not al-
       ready have one available

SYNOPSIS

       Status XkbAllocCompatMap (XkbDescPtr xkb, unsigned int  which,  unsigned
              int num_si);

ARGUMENTS
       xkb    keyboard description in which to allocate compat map

       which  mask of compatibility map components to allocate

       num_si number of symbol interpretations to allocate

DESCRIPTION
       xkb  specifies the keyboard description for which compatibility maps are
       to be allocated. The compatibility map  is  the  compat  field  in  this
       structure.

       which  specifies  the  compatibility map components to be allocated (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

       num_si  specifies  the total number of entries to allocate in the symbol
       interpretation vector (xkb.compat.sym_interpret).

       XkbAllocCompatMap returns Success if  successful,  BadMatch  if  xkb  is
       NULL,  or BadAlloc if errors are encountered when attempting to allocate
       storage.

STRUCTURES
           typedef struct {
               KeySym            sym;          /* keysym of interest or NULL */
               unsigned char     flags;        /* XkbSI_AutoRepeat, XkbSI_LockingKey */
               unsigned char     match;        /* specifies how mods is interpreted */
               unsigned char     mods;         /* modifier bits, correspond to eight real modifiers */
               unsigned char     virtual_mod;  /* 1 modifier to add to key virtual mod map */
               XkbAnyAction      act;          /* action to bind to symbol position on key */
           } XkbSymInterpretRec,*XkbSymInterpretPtr;

DIAGNOSTICS
       BadAlloc       Unable to allocate storage

       BadMatch       A compatible version of Xkb  was  not  available  in  the
                      server  or an argument has correct type and range, but is
                      otherwise invalid

NOTES
       Note that symbol interpretations in a compatibility map (the  sym_inter-
       pret  vector  of XkbSymInterpretRec structures) are also allocated using
       this same function. To ensure that there is sufficient space in the sym-
       bol interpretation vector for entries to be added, use XkbAllocCompatMap
       specifying which as XkbSymInterpretMask and the number  of  free  symbol
       interpretations needed in num_si.
