.SH "NAME"
XSetDeviceValuators \- initialize the valuators on an extension input device
.SH "SYNOPSIS"
.sp
.nf
#include
.fi
.sp
.nf
XSetDeviceValuators( Display *display,
XDevice *device,
int *valuators,
int first_valuator,
int num_valuators);
.fi
.sp
.nf
display
Specifies the connection to the X server\&.
.fi
.sp
.nf
device
Specifies the device whose valuators are to be
initialized\&.
.fi
.sp
.nf
valuators
Specifies a pointer to an array of integer values to be
used to initialize the device valuators\&.
.fi
.sp
.nf
first_valuator
Specifies the first valuator to be set\&. Valuators are
numbered beginning with zero\&.
.fi
.sp
.nf
num_valuators
Specifies the number of valuators to be set\&.
.fi
.SH "DESCRIPTION"
.sp
.if n \{\
.RS 4
.\}
.nf
The XSetDeviceValuators request sets the current values of the
valuators of an input device\&. The valuators in the range
first_valuator to (first_valuator + num_valuators) are set to
the specified values\&. Valuators are numbered beginning with 0\&.
Not all input devices support initialization of valuator
values\&. If this request is made to a device that does not
support valuators initialization, a BadMatch error will occur\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
If the request succeeds, a status of Success is returned\&. If
another client has the device grabbed, a status of
AlreadyGrabbed is returned\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
XSetDeviceValuators can generate a BadLength, BadDevice,
BadMatch, or BadValue error\&.
.fi
.if n \{\
.RE
.\}
.SH "DIAGNOSTICS"
.sp
.if n \{\
.RS 4
.\}
.nf
BadDevice
An invalid device was specified\&. The specified device
does not exist or has not been opened by this client via
XOpenInputDevice\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
BadMatch
This error may occur if an XSetDeviceValuators request
is made specifying a device that has no valuators and
reports no axes of motion, or if such a request is made
specifying a device that does not support valuator
initialization\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
BadValue
An invalid first_valuator or num_valuators values was
specified\&.
.fi
.if n \{\
.RE
.\}
