.SH DESCRIPTION
|
|
.LP
|
|
The
|
|
.I XkbFreeServerMap
|
|
function frees the specified components of server map in the XkbDescRec
|
|
structure specified by the
|
|
.I xkb
|
|
parameter and sets the corresponding structure component values to NULL. The
|
|
.I which parameter specifies a combination of the server map masks and is a
|
|
bitwise inclusive OR
|
|
of the masks listed in Table 1. If
|
|
.I free_all
|
|
is True,
|
|
.I which
|
|
is ignored and
|
|
.I XkbFreeServerMap
|
|
frees every non-NULL structure component in the server map, frees the
|
|
XkbServerMapRec structure
|
|
referenced by the
|
|
.I server
|
|
member of the
|
|
.I xkb
|
|
parameter, and sets the
|
|
.I server
|
|
member to NULL.

The complete description of an Xkb keyboard is given by an XkbDescRec. The
|
|
component

structures in the XkbDescRec represent the major Xkb components.

The
|
|
.I display
|
|
field points to an X display structure. The
|
|
.I flags field is private to the library: modifying
|
|
.I flags
|
|
may yield unpredictable results. The
|
|
.I device_spec
|
|
field specifies the device identifier of the keyboard input device, or
|
|
XkbUseCoreKeyboard, which specifies the core keyboard device. The
|
|
.I min_key_code
|
|
and
|
|
.I max_key_code
|
|
fields specify the least and greatest keycode that can be returned by the
|
|
keyboard.
|
|
|
|
Each structure component has a corresponding mask bit that is used in function
|
|
calls to
|
|
indicate that the structure should be manipulated in some manner, such as
|
|
allocating it
|
|
or freeing it. These masks and their relationships to the fields in the
|
|
XkbDescRec are
|
|
shown in Table 2.
