XSetPointerMapping(3) XLIB FUNCTIONS XSetPointerMapping(3)
NAME
XSetPointerMapping, XGetPointerMapping - manipulate pointer settings
SYNTAX
int XSetPointerMapping(Display *
display, _Xconst 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.
