NAME

6       XSetPointerMapping, XGetPointerMapping - manipulate pointer settings
7

SYNTAX

9       int  XSetPointerMapping(Display  *display, _Xconst unsigned char map[],
10              int nmap);
11
12       int XGetPointerMapping(Display *display,  unsigned  char  map_return[],
13              int nmap);
14

ARGUMENTS

16       display   Specifies the connection to the X server.
17
18       map       Specifies the mapping list.
19
20       map_return
21                 Returns the mapping list.
22
23       nmap      Specifies the number of items in the mapping list.
24

DESCRIPTION

26       The XSetPointerMapping function sets the mapping of the pointer.  If it
27       succeeds, the X server generates a MappingNotify event, and  XSetPoint‐
28       erMapping  returns  MappingSuccess.  Element map[i] defines the logical
29       button number for the physical button i+1.  The length of the list must
30       be the same as XGetPointerMapping would return, or a BadValue error re‐
31       sults.  A zero element disables a button,  and  elements  are  not  re‐
32       stricted  in  value by the number of physical buttons.  However, no two
33       elements can have the same nonzero value, or a BadValue error  results.
34       If  any  of  the buttons to be altered are logically in the down state,
35       XSetPointerMapping returns MappingBusy, and the mapping is not changed.
36
37       XSetPointerMapping can generate a BadValue error.
38
39       The XGetPointerMapping function returns  the  current  mapping  of  the
40       pointer.   Pointer  buttons are numbered starting from one.  XGetPoint‐
41       erMapping returns the  number  of  physical  buttons  actually  on  the
42       pointer.   The  nominal  mapping for a pointer is map[i]=i+1.  The nmap
43       argument specifies the length of the array where the pointer mapping is
44       returned, and only the first nmap elements are returned in map_return.

DIAGNOSTICS

47       BadValue  Some numeric value falls outside the range of values accepted
48                 by the request.  Unless a specific range is specified for  an
49                 argument,  the  full  range defined by the argument's type is
50                 accepted.  Any argument defined as a set of alternatives  can
51                 generate this error.
