X Version 11 (Release 5)
XSetPointerMapping(XS)
XSetPointerMapping --
manipulate pointer settings
Syntax
int XSetPointerMapping(display, map, nmap)
Display *display;
unsigned char map[];
int nmap;
int XGetPointerMapping(display, map_return, nmap)
Display *display;
unsigned char map_return[];
int nmap;
Arguments
display-
Specifies the connection to the X server.
map-
Specifies the mapping list.
map_return-
Returns the mapping list.
nmap-
Specifies the number of items in the mapping list.
Description
The XSetPointerMapping
function sets the mapping of the pointer.
If it succeeds, the X server generates a
MappingNotify event, and
XSetPointerMapping returns MappingSuccess.
Element map[i] defines the logical button number for
the physical button i+1.
The length of the list must be the same as
XGetPointerMapping would return,
or a ``BadValue'' error results.
A zero element disables a button, and elements are not
restricted in value by the number of physical buttons.
However, no two elements can have the same nonzero value,
or a ``BadValue'' error results.
If any of the buttons to be altered are logically in the down state,
XSetPointerMapping returns MappingBusy,
and the mapping is not changed.
XSetPointerMapping can generate a ``BadValue'' error.
The XGetPointerMapping
function returns the current mapping of the pointer.
Pointer buttons are numbered starting from one.
XGetPointerMapping
returns the number of physical buttons actually on the pointer.
The nominal mapping for a pointer is map[i]=i+1.
The nmap argument specifies the length of the array where
the pointer mapping is returned, and only the first nmap
elements are returned in map_return.
Diagnostics
``BadValue''-
Some numeric value falls outside the range of values accepted by the request.
Unless a specific range is specified for an argument, the full range defined
by the argument's type is accepted. Any argument defined as a set of
alternatives can generate this error.
