.TP
.I \- free_map
True => free XkbCompatMap structure itself

is an inclusive OR of the bits shown in Table 1.

.TE
.I free_map
indicates whether the XkbCompatMap structure itself should be freed. If
.I free_map
is True,
.I which
is ignored, all non-NULL compatibility map components are freed, and the
.I compat
field in the XkbDescRec referenced by
.I xkb
is set 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 outlined in Figure 1.1.
.nf
typedef struct {
struct _XDisplay * display; /\(** connection to X server */
unsigned short flags; /\(** private to Xkb, do not modify */
unsigned short device_spec; /\(** device of interest */

} XkbDescRec, *XkbDescPtr;
.fi
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.
The other fields specify structure components of the keyboard description and are
described in detail in other sections of this document. Table 2 identifies the
subsequent sections of this document that discuss the individual components of the
XkbDescRec.

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 3.
