       XkbAddGeomKeyAlias - Add one key alias to an existing keyboard geometry description


       XkbKeyAliasPtr XkbAddGeomKeyAlias (XkbGeometryPtr geom, char *alias, char *real);


       - geom geometry to be updated

       - alias
              alias to be added

       - real real name to be bound to the new alias


       Xkb  provides functions to add a single new element to the top-level keyboard geometry. In
       each case the num_ * fields of the corresponding structure  is  incremented  by  1.  These
       functions  do  not  change  sz_*  unless there is no more room in the array. Some of these
       functions fill in the values of the element's structure  from  the  arguments.  For  other
       functions, you must explicitly write code to fill the structure's elements.

       The  top-level  geometry  description  includes a list of geometry properties.  A geometry
       property associates an arbitrary string with an  equally  arbitrary  name.  Programs  that
       display  images  of  keyboards  can  use  geometry  properties  as hints, but they are not
       interpreted by Xkb. No other geometry structures refer to geometry properties.

       XkbAddGeomKeyAlias adds one key alias with the value  alias  to  the  geometry  geom,  and
       associates it with the key whose real name is real. XkbAddGeomKeyAlias returns NULL if any
       of the parameters is empty or if it was not able to  allocate  space  for  the  alias.  To
       allocate  space  for  an  arbitrary  number  of  aliases,  use  the XkbAllocGeomKeyAliases


           typedef struct {
               char            real[XkbKeyNameLength];   /∗ this key name must be in the keys array */
               char            alias[XkbKeyNameLength];  /∗ symbolic key name as alias for the key */
           } XkbKeyAliasRec,*XkbKeyAliasPtr;
