XkbSetNames(3)			 XKB FUNCTIONS			XkbSetNames(3)

NAME
       XkbSetNames - Change the symbolic names in the server

SYNOPSIS
       Bool XkbSetNames ( dpy, which, first_type, num_types , xkb )
	     Display * dpy;
	     unsigned int which;
	     unsigned int first_type;
	     unsigned int num_types;
	     XkbDescPtr xkb;

ARGUMENTS
       - dpy  connection to the X server

       - which
	      mask of names or map components to be changed

       - first_type
	      first type whose name is to be changed

       - num_types
	      number of types for which names are to be changed

       - xkb  keyboard description from which names are to be taken

DESCRIPTION
       To  change  the symbolic names in the server, first modify a local copy
       of the keyboard description and then use	 either	 XkbSetNames,  or,  to
       save   network  traffic,	 use  a	 XkbNameChangesRecstructure  and  call
       XkbChangeNames to download the changes to the server.  XkbSetNames  and
       XkbChangeNames can generate BadAlloc, BadAtom, BadLength, BadMatch, and
       BadImplementation errors.

       Use XkbSetNames to change many names at the same time. For each bit set
       in  which,  XkbSetNames takes the corresponding value (or values in the
       case of arrays) from the keyboard description xkb and sends it  to  the
       server.

       The  first_type	and  num_types	arguments are used only if XkbKeyType‐
       NamesMask or XkbKTLevelNamesMask is set in which and specify  a	subset
       of  the	types  for which the corresponding names are to be changed. If
       either or both of these mask bits are set but the specified  types  are
       illegal, XkbSetNames returns False and does not update any of the names
       specified in which.  The specified types are illegal if	xkb  does  not
       include	a  map	component or if first_type and num_types specify types
       that are not defined in the keyboard description.

STRUCTURES
       The XkbNameChangesRec allows applications to identify  small  modifica‐
       tions to the symbolic names and effectively reduces the amount of traf‐
       fic sent to the server:

	   typedef struct _XkbNameChanges {
	       unsigned int   changed;		/∗ name components that have changed */
	       unsigned char  first_type;	/∗ first key type with a new name */
	       unsigned char  num_types;	/∗ number of types with new names */
	       unsigned char  first_lvl;	/∗ first key type with new level names
       */
	       unsigned char  num_lvls;		/∗ number of key types with new level
       names */
	       unsigned char  num_aliases;	/∗ if key aliases changed, total number
       of key aliases */
	       unsigned char  num_rg;		/∗ if radio groups changed, total
       number of radio groups */
	       unsigned char  first_key;	/∗ first key with a new name */
	       unsigned char  num_keys;		/∗ number of keys with new names */
	       unsigned short changed_vmods;	/∗ mask of virtual modifiers for which
       names have changed */
	       unsigned long  changed_indicators; /∗ mask of indicators for which names
       were changed */
	       unsigned char  changed_groups;	  /∗ mask of groups for which names
       were changed */
	   } XkbNameChangesRec, *XkbNameChangesPtr

       The changed field specifies the name components that have  changed  and
       is the bitwise inclusive OR of the valid names mask bits defined in Ta‐
       ble 1. The rest of the fields in the structure specify the ranges  that
       have changed for the various kinds of symbolic names, as shown in Table
       2.

       Xkb provides several functions that work with symbolic names.  Each  of
       these  functions uses a mask to specify individual fields of the struc‐
       tures described above. These  masks  and	 their	relationships  to  the
       fields in a keyboard description are shown in Table 1.

DIAGNOSTICS
       BadAlloc	      Unable to allocate storage

       BadAtom	      A name is neither a valid Atom or None

       BadImplementation
		      Invalid reply from server

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

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