XSetPointerMapping(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 function sets the mapping of the pointer. If it succeeds, the X server generates a event, and returns Element map[i] defines the logical button number for the physical button i+1. The length of the list must be the same as would return, or a 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 error results. If any of the buttons to be altered are logically in the down state, returns and the mapping is not changed.

can generate a error.

The function returns the current mapping of the pointer. Pointer buttons are numbered starting from one. 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

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.
