NAME
XSetPointerMapping, XGetPointerMapping - manipulate pointer settings
SYNTAX
int XSetPointerMapping(Display *display, unsigned char map[], int
nmap);
int XGetPointerMapping(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.
