 * @memberOf wsemi
 * @param {String} pah 輸入檔案路徑字串
 * @param {Buffer|TypedArray|DataView} data 輸入檔案內容資料
 * @param {Object|String} [opt={}] 輸入寫入設定物件或字串，可給予writeFileSync設定物件，或是編碼字串(例如'utf8')，預設{}
 * @param {String} [opt.encoding='utf8'] 輸入編碼字串，預設'utf8'
 * @param {Integer} [opt.mode=0o666] 輸入寫入模式數字，預設0o666
 * @param {String} [opt.flag='w'] 輸入寫入標誌字串，預設'w'
 * @returns {Object} 回傳結果物件，提供鍵success代表成功訊息，提供鍵error代表錯誤訊息
 * @example
 * need test in nodejs.
 *
 * let test = () => {
 *
 *     let ms = []
