dchashnext0()

subroutine dc_hash::next::dchashnext0	(	type(hash), intent(inout)	hashv,
		character(*), intent(out)	key,
		character(*), intent(out), optional	value,
		logical, intent(out)	end )

ハッシュから次のキーと値のペアを取得

hashv の内容を key と value に返します. 詳しくは DCHashRewind を参照してください.

Parameters

[in,out]	hashv	ハッシュ変数
[out]	key	キー文字列
[out]	value	値文字列 (省略可能)
[out]	end	全エントリを走査し終えた場合に .true. を返す
