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 XWIN 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 XWIN server generates a Map-
pingNotify event, and XSetPointerMapping returns MappingSuc-
cess.  Elements of the list are indexed starting from one.
The length of the list must be the same as XGetPointerMap-
ping 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 physi-
cal 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, XSet-
PointerMapping 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 argu-
     ment 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 gen-
          erate this error.
