You can write trace data to a file continuously as an extension to the in-storage trace, but instead of one buffer per thread, at least two buffers per thread are allocated.
可以连续地将跟踪数据写到文件中，作为存储内跟踪的扩展；但是在这种情况下不是为每个线程分配一个缓冲区，而是至少分配两个。
A ring buffer is a logging technique for applications whereby the relevant data to be logged is kept in memory instead of writing it to a file on a disk every time.
循环缓冲区是一种用于应用程序的日志记录技术，它可以将相关的数据保存在内存中，而不是每次都将其写入到磁盘上的文件中。
Most of the file systems communicate through a buffer cache, which is a cache that optimizes access to the physical devices by caching recently touched data.
大多数文件系统都通过缓冲区缓存来相互通信，这种缓存通过缓存最近使用的数据来优化对物理设备的访问。
Users can stream the output data into a string, an internal buffer, the standard output, or a file.
用户可以使这些输出数据流入字符串、内部缓冲区、标准输出或文件。
Listing 4 and Listing 5 show samples of writing the data to a ring buffer and dumping its contents to file.

Use the buffer file system to process lots of data of project and table management.
该文介绍使用缓冲文件系统处理工程应用中的大量数据，及日常生活的二维表管理。
Stream I/O Model This leads to efficient I/O but beware: data written to a buffer does not appear in a file (or device) until the buffer is flushed or written out. (/n does this).
流是（表达）读写数据的一种可移植的方法，它为一般的I/O操作提供了灵活有效的手段。
