23 which specifies the compatibility map components to be freed (see
24 XkbGetCompatMap). which is an inclusive OR of the bits shown in Table
25 1.

35 free_map indicates whether the XkbCompatMap structure itself should be
37 freed. If free_map is True, which is ignored, all non-NULL compatibil‐
38 ity map components are freed, and the compat field in the XkbDescRec
39 referenced by xkb is set to NULL.

48 The complete description of an Xkb keyboard is given by an XkbDescRec.
51 The component structures in the XkbDescRec represent the major Xkb com‐
52 ponents outlined in Figure 1.1.
53 typedef struct {
55 struct _XDisplay * display; /∗ connection to X server */
56 unsigned short flags; /∗ private to Xkb, do not modify */
57 unsigned short device_spec; /∗ device of interest */

67 } XkbDescRec, *XkbDescPtr;
68 The display field points to an X display structure. The flags field is
70 private to the library: modifying flags may yield unpredictable
71 results. The device_spec field specifies the device identifier of the
72 keyboard input device, or XkbUseCoreKeyboard, which specifies the core
73 keyboard device. The min_key_code and max_key_code fields specify the
74 least and greatest keycode that can be returned by the keyboard. The
75 other fields specify structure components of the keyboard description
76 and are described in detail in other sections of this document. Table 2
77 identifies the subsequent sections of this document that discuss the
78 individual components of the XkbDescRec.

92 Each structure component has a corresponding mask bit that is used in
94 function calls to indicate that the structure should be manipulated in
95 some manner, such as allocating it or freeing it. These masks and their
96 relationships to the fields in the XkbDescRec are shown in Table 3.
