NAME

6       XSetDeviceValuators - initialize the valuators on an extension input
7       device

SYNOPSIS

10       #include <X11/extensions/XInput.h>
11
12       XSetDeviceValuators( Display *display,
13                            XDevice *device,
14                            int *valuators,
15                            int first_valuator,
16                            int num_valuators);
17
18       display
19              Specifies the connection to the X server.
20
21       device
22              Specifies the device whose valuators are to be
23              initialized.
24
25       valuators
26              Specifies a pointer to an array of integer values to be
27              used to initialize the device valuators.
28
29       first_valuator
30              Specifies the first valuator to be set. Valuators are
31              numbered beginning with zero.
32
33       num_valuators
34              Specifies the number of valuators to be set.
35

DESCRIPTION

37           The XSetDeviceValuators request sets the current values of the
38           valuators of an input device. The valuators in the range
39           first_valuator to (first_valuator + num_valuators) are set to
40           the specified values. Valuators are numbered beginning with 0.
41           Not all input devices support initialization of valuator
42           values. If this request is made to a device that does not
43           support valuators initialization, a BadMatch error will occur.
44
45           If the request succeeds, a status of Success is returned. If
46           another client has the device grabbed, a status of
47           AlreadyGrabbed is returned.
48
49           XSetDeviceValuators can generate a BadLength, BadDevice,
50           BadMatch, or BadValue error.

DIAGNOSTICS

53           BadDevice
54                  An invalid device was specified. The specified device
55                  does not exist or has not been opened by this client via
56                  XOpenInputDevice.
57
58           BadMatch
59                  This error may occur if an XSetDeviceValuators request
60                  is made specifying a device that has no valuators and
61                  reports no axes of motion, or if such a request is made
62                  specifying a device that does not support valuator
63                  initialization.
64
65           BadValue
66                  An invalid first_valuator or num_valuators values was
67                  specified.
