需要一个良好的解决方案用于同步读写 [英] need a good solution for synchronized read write

问题描述

我有一个线程（WRITER），在输入数据到达时连续填充缓冲区（在我的例子中是一个向量）。
我有另一个线程（READER）定期检查缓冲区的输入数据，并清除缓冲区处理数据完成后。
一旦我看到一个实现，建议有两个缓冲区（A和B）。 WRITER写入缓冲区A，当它是读取数据的时间时，READER接管缓冲区A，并且WRITER开始读取B ...并且这种翻转继续。

我googled为参考或示例代码，但找不到任何。
你能建议我参考吗？ / div>

最简单的解决方案是在Boost库的帮助下使用同步队列。

on CodeProject 此处，以及Google上的无数示例。

I have a thread(WRITER) that continuously populates a buffer(a vector in my case) as the incoming data arrive. And i have another thread(READER) that periodically checks the buffer for incoming data and clears the buffer after processing data is done. Once I saw an implementation that suggested to have two buffers (A and B) instead. the WRITER writes into buffer A, and when it is the time for reading the data, the READER takes over buffer A and WRITER starts reading into B...and this flipping continues.

I googled for a reference or sample code but couldn't find any. Can you please suggest me a reference? Also, is this the best and simplest approach?

thank you

解决方案

The simplest solution is using a syncronized queue with the help of the Boost libraries.

There is an article about this on CodeProject here, and countless examples on Google.
