Romaji-kana conversion is effected by using a Romaji-kana conversion table created by mkromdic(1). RkCloseRoma closes this Romaji-kana conversion table. romaji specifies the pointer to the Romaji-kana conversion table returned by RkOpenRoma(3).
RkwCloseRoma is the similar function of RkCloseRoma. This is provided just because of naming convention.
