XSetPointerMapping(3X1Version 11 (ReleaseXSetPointerMapping(3X11)
NAME
XSetPointerMapping, XGetPointerMapping - 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

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.
