XSetPointerMapping(3X11)XSetPointerMapping(3X11)NAME
XSetPointerMapping, XGetPointerMapping - manipulate pointer settings
SYNOPSIS
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
Specifies the connection to the X server. Specifies the mapping list.
Returns the mapping list. 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 XSetPoint‐
erMapping 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. XGetPoint‐
erMapping 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
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.
