如何检查进程是在进行网络还是文件IO？ [英] How to check if a process is doing Network or File IO?

问题描述

我正在编写一个应用程序，必须弄清楚一个进程是否正在执行任何类型的IO，并且必须暂停该进程。现在我知道如何暂停和恢复该过程，但我不知道如何检查它是否正在执行IO操作。我如何解决这个问题？

解决方案

你可以通过一个特殊的标志安全保护你的IO进程来间接地做到这一点，所以知道，正在运行什么。< br $>


元代码：

  bool  ioGlobalFlag =  false ;  //   static var或Lock / Mutex  
 
  ///  稍后在您的代码中
  ioGlobalFlag =  true ; 
  //  这里有你的io  
 .... 
 
  //  现已准备就绪 
 ioGlobalFlag =  false ; 

考虑在单独的线程中完成所有操作，但需要锁定或互斥锁。

Hi, I am writing an application that has to figure out whether a process is doing any kind of IO, and has to pause that process if it is. Now I know how to pause and resume the process but I don't know how to check if it is performing IO operations. How do I figure that out?

解决方案

You can do it indirectly, by safe-guarding your IO-processes with a special flag so know, what is running.

Meta-code:

bool ioGlobalFlag = false;//static var or Lock/Mutex

///later in your code
 ioGlobalFlag = true;
//here comes your io
....

//io now ready
 ioGlobalFlag = false;

Consider doing it all in a seperate thread, but than you need locking or a mutex.
