XSetPointerMapping


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 XSetPointerMapping function sets the mapping of the pointer. If it succeeds, the X server generates a Map- pingNotify 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 map- ping of the pointer. Pointer buttons are numbered start- ing 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 map- ping 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 spe- cific 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.
