XkbChangeMap(3)                                 XKB FUNCTIONS                                XkbChangeMap(3)



NAME
       XkbChangeMap  -  Update  only  partial  components  of a keyboard description, modify the appropriate
       fields in the server and map components of a local copy of the keyboard description

SYNOPSIS
       Bool XkbChangeMap ( dpy, xkb, changes )
             Display * dpy;
             XkbDescPtr xkb;
             XkbMapChangesPtr changes;

ARGUMENTS
       - dpy  connection to X server

       - xkb  description from which new values are taken

       - changes
              identifies component parts to update

DESCRIPTION
       To update only partial components of a keyboard description, modify the  appropriate  fields  in  the
       server and map components of a local copy of the keyboard description, then call XkbChangeMap with an
       XkbMapChangesRec structure indicating which components have changed.

       XkbChangeMap copies any components specified by the changes structure from the keyboard  description,
       xkb, to the X server specified by dpy.

       If  any  components  specified  by changes are not present in the xkb parameter, XkbChangeMap returns
       False. Otherwise, it sends a request to the server and returns True.

       XkbChangeMap can generate BadAlloc, BadLength, and BadValue protocol errors.

RETURN VALUES
       True           The XkbChangeMap function returns True if the  components  specified  by  changes  are
                      present in the xkb parameter.

       False          The XkbChangeMap function returns False if the components specified by changes are not
                      present in the xkb parameter.

STRUCTURES
       Use the XkbMapChangesRec structure to identify and track partial modifications to the mapping  compo-nents components
       nents and to reduce the amount of traffic between the server and clients.

           unsigned char    num_key_explicit;   /* # explicit entries changed */
           KeyCode          first_modmap_key;   /* first key whose modmap entry changed

DIAGNOSTICS
       BadAlloc       Unable to allocate storage

       BadLength      The  length  of a request is shorter or longer than that required to minimally contain
                      the arguments

       BadValue       An argument is out of range
