XGetPointerMapping()					  XGetPointerMapping()

Name
  XGetPointerMapping – get the pointer button mapping.

Synopsis
  int XGetPointerMapping(display, map_return, nmap)
	Display *display;
	unsigned char map_return[];
	int nmap;

Arguments
  display   Specifies	a  connection  to  an  X  server;  returned  from
	    XOpenDisplay().

  map_return
	    Returns the mapping list.  Array begins with map_return[].

  nmap	    Specifies the number of items in mapping list.

Returns
  The number of elements in the pointer list.

Description
  XGetPointerMapping() returns the current mapping of  the  pointer  but‐
  tons.	 Information is returned in both the arguments and the function's
  return value.	 map_return is an array of the numbers of the buttons  as
  they	are  currently mapped.	Elements of the list are indexed starting
  from 1.  The nominal mapping for a pointer  is  the  identity	 mapping:
  map_return[i]=i+1.   If map[2]=2, it means that the third physical but‐
  ton triggers the second logical button.

  nmap indicates the desired number of button mappings.

  The return value of the function is the actual number	 of  elements  in
  the pointer list, which may be greater or less than nmap.
