NAME

6       XkbFreeCompatMap  -  Free  an entire compatibility map or selected por‐
7       tions of one
8

SYNOPSIS

10       void  XkbFreeCompatMap  (XkbDescPtr  xkb,  unsigned  int  which,   Bool
11              free_map);
12

ARGUMENTS

14       - xkb  Xkb description in which to free compatibility map
15
16       - which
17              mask of compatibility map components to free
18
19       - free_map
20              True => free XkbCompatMap structure itself
21

DESCRIPTION

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.

32       XkbSymInterpMask     (1<<0)   Symbol interpretations

34       XkbAllCompatMask     (0x3)    All compatibility map components
35
36       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.

50       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.

69       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.

93       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.
