XkbSetNames \- Change the symbolic names in the server

.SH ARGUMENTS
.TP
.I \- dpy
connection to the X server
.TP
.I \- which
mask of names or map components to be changed
.TP
.I \- first_type
first type whose name is to be changed
.TP
.I \- num_types
number of types for which names are to be changed
.TP
.I \- xkb
keyboard description from which names are to be taken
.SH DESCRIPTION
.LP
To change the symbolic names in the server, first modify a local copy of the
keyboard description and then
use either
.I XkbSetNames,
or, to save network traffic, use a XkbNameChangesRecstructure and call
.I XkbChangeNames
to download the changes to the server.
.I XkbSetNames
and
.I XkbChangeNames
can generate BadAlloc, BadAtom, BadLength, BadMatch, and BadImplementation
errors.
Use
.I XkbSetNames
to change many names at the same time. For each bit set in
.I which, XkbSetNames
takes the corresponding value (or values in the case of arrays) from the
keyboard description
.I xkb
and sends it to the server.
The
.I first_type
and
.I num_types
arguments are used only if XkbKeyTypeNamesMask or XkbKTLevelNamesMask is set in
.I 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,
.I XkbSetNames
returns False and does not update any of the names specified in
.I which.
The specified types are illegal if
.I xkb
does not include a map component or if
.I first_type
and
.I num_types
specify types that are not defined in the keyboard description.
.SH STRUCTURES
.LP
The XkbNameChangesRec allows applications to identify small modifications to the
symbolic names and
effectively reduces the amount of traffic sent to the server:
.nf
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
.fi
The
.I changed
field specifies the name components that have changed and is the bitwise
inclusive OR of the valid names
mask bits defined in Table 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 structures described above. These masks and
their relationships to the
fields in a keyboard description are shown in Table 1.
