如何在循环中将数据写入文件

Question

我正在开发一个Streaming，它将从Fx3板流式传输数据。

我想在将数据从Streamer写入文件时将数据从Streamer写入PC Memory(files),，数据写入文件 但我希望在第一个文件n内再次找到一些没有文件后写，所以任何人都可以帮我解决这个问题。

if (Save == true)   //Check if save Button is marked

        const int sizeLimitInBytes = 360960*16;

            {

                index++;
