- 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.
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.
- 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.
