gdncvarputattrchar()

subroutine gdncvarputattrchar	(	type(gd_nc_variable), intent(in)	var,
		character(len = *), intent(in)	name,
		character(len = *), intent(in)	val,
		character(len = *), intent(in), optional	xtype,
		logical, intent(out), optional	err
	)

文字属性値を設定

変数に文字属性を設定します。xtype が指定された場合、 値はその数値型に変換されてから格納されます。 name が '+' で始まる場合、グローバル属性として扱われます。 空の value は属性を削除します。

Parameters

[in]	var	変数ハンドル
[in]	name	属性名
[in]	val	設定する文字値
[in]	xtype

iline 45 変換先の型 (省略可能)

Parameters

[out]

err

エラーフラグ (省略可能)
