.\"0 Specifies the denominator for the acceleration multiplier.

.IP \fIaccel_denominator_return\fP 1i
.\"0 Returns the denominator for the acceleration multiplier.
アクセラレーションの倍率の分母が返される。
.IP \fIaccel_numerator\fP 1i
.\"0 Specifies the numerator for the acceleration multiplier.
アクセラレーションの倍率の分子を指定する。
.IP \fIaccel_numerator_return\fP 1i
.\"0 Returns the numerator for the acceleration multiplier.

.IP \fIdisplay\fP 1i
.\"0 Specifies the connection to the X server.
X サーバへの接続を指定する。
.IP \fIdo_accel\fP 1i
.\"0 Specifies a Boolean value that controls whether the values for 
.\"0 the accel_numerator or accel_denominator are used.

.IP \fIthreshold\fP 1i

.IP \fIthreshold_return\fP 1i

.SH 説明
.\"0 The
.\"0 .ZN XChangePointerControl
.\"0 function defines how the pointing device moves.
関数
.ZN XChangePointerControl
は、ポインティングデバイスがどのように動くか定義する。
.\"0 The acceleration, expressed as a fraction, is a
.\"0 multiplier for movement. 
分母で表現されるアクセラレーションは移動量にかける倍率である。
.\"0 For example,
.\"0 specifying 3/1 means the pointer moves three times as fast as normal.
例えば 3/1 を指定すると、ポインタは通常の 3 倍の速さで移動する。
.\"0 The fraction may be rounded arbitrarily by the X server.  
X サーバによって、端数は任意に丸められることがある。
.\"0 Acceleration
.\"0 only takes effect if the pointer moves more than threshold pixels at
.\"0 once and only applies to the amount beyond the value in the threshold argument.
ポインタが一度に閾値の個数以上のピクセル移動し、引き数 threshold の値を
越える量を移動しようとした場合に限って、アクセラレーションは有効となる。
.\"0 Setting a value to \-1 restores the default.
値に \-1 を指定するとデフォルト値に戻る。
.\"0 The values of the do_accel and do_threshold arguments must be 
.\"0 .ZN True 
.\"0 for the pointer values to be set,
.\"0 or the parameters are unchanged.
ポインタの値をセットするには、引き数 do_accel と do_threshold は
.ZN True
でなければならない。そうでない場合には、パラメータは変化しない。
.\"0 Negative values (other than \-1) generate a
.\"0 .ZN BadValue
.\"0 error, as does a zero value
.\"0 for the accel_denominator argument.
負の値(\-1 を除く)の場合には、エラー
.ZN BadValue
となる。
引き数 accel_denominator が 0 の場合も同じエラーになる。
.LP
.\"0 .ZN XChangePointerControl
.\"0 can generate a
.\"0 .ZN BadValue 
.\"0 error.
.ZN XChangePointerControl
はエラー
.ZN BadValue 
を起こすことがある。
.LP
.\"0 The
.\"0 .ZN XGetPointerControl
.\"0 function returns the pointer's current acceleration multiplier
.\"0 and acceleration threshold.
関数
.ZN XGetPointerControl
は、ポインタのアクセラレーションの倍率と閾値の現在の値を返す。
.SH 返り値
.TP 1i
.ZN BadValue
.\"0 Some numeric value falls outside the range of values accepted by the request.
.\"0 Unless a specific range is specified for an argument, the full range defined
.\"0 by the argument's type is accepted.  Any argument defined as a set of
.\"0 alternatives can generate this error.
指定された数値の中にリクエストの許容範囲を越えているものがある。引き数に対
して特定の範囲が指定されていない限り、引き数の型で定義されている全ての範
囲が許される。選択肢として定義されている引き数はこのエラーを起こすことが
ある。
