X Version 11 (1 September 1988) XSetPointerMapping(XS)
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. Elements of the list are indexed starting
from one. The length of the list must be the same as
XGetPointerMapping would return, or a BadValue error
results. The index is a core button number, and the element
of the list defines the effective number. 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. Elements of the list are indexed starting
from one. XGetPointerMapping returns the number of physical
buttons actually on the pointer. The nominal mapping for a
pointer is the identity mapping: map[i]=i. 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.
