XSetPointerMapping(3)

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 XSetPoint-
       erMapping 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.  XGetPoint-
       erMapping 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.
