.SH DESCRIPTION
|
||
|
.LP
|
||
|
There are two ways to make changes to map components: either change a local copy
|
||
|
of the keyboard map and call
|
||
|
.I XkbSetMap
|
||
|
to send the modified map to the server, or, to reduce network traffic, use an
|
||
|
XkbMapChangesRec structure and call
|
||
|
.I XkbChangeMap.
|
||
|
|
||
|
Use
|
||
|
.I XkbSetMap
|
||
|
to send a complete new set of values for entire components (for example, all
|
||
|
symbols, all actions, and so on) to the server. The
|
||
|
.I which
|
||
|
parameter specifies the components to be sent to the server, and is a bitwise
|
||
|
inclusive OR of the masks listed in Table 1. The
|
||
|
.I xkb
|
||
|
parameter is a pointer to an XkbDescRec structure and contains the information
|
||
|
to be copied to the server. For each bit set in the
|
||
|
.I which
|
||
|
parameter,
|
||
|
.I XkbSetMap
|
||
|
takes the corresponding structure values from the
|
||
|
.I xkb
|
||
|
parameter and sends it to the server specified by
|
||
|
.IR dpy .
|
||
|
|
||
|
If any components specified by
|
||
|
.I which
|
||
|
are not present in the
|
||
|
.I xkb
|
||
|
parameter,
|
||
|
.I XkbSetMap
|
||
|
returns False. Otherwise, it sends the update request to the server and returns
|
||
|
True.
|
||
|
.I XkbSetMap
|
||
|
can generate BadAlloc, BadLength, and BadValue protocol errors.
|
||
|
|
||
|
Key types, symbol maps, and actions are all interrelated; changes in one require
|
||
|
changes in the others. Xkb provides functions to make it easier to edit these
|
||
|
components and handle the interdependencies. Table 1
|
||
|
lists these helper functions and provides a pointer to where they are defined.

The

field identifies the map components that have changed in an XkbDescRec structure
|
||
|
and may contain any of the
|
||
|
bits in Table 1, which are also shown in Table 2. Every 1 bit in
|
||
|
.I changed
|

also identifies which other fields in the XkbMapChangesRec structure contain
|
||
|
valid values, as indicated in

Table 2. The

.I min_key_code

by the server whenever it returns the data for an XkbMapChangesRec.

Each structure component has a corresponding mask bit that is used in function

allocating it or freeing it. These masks and their relationships to the fields in the
