子进程

• When the caller reads from the redirected stream of a child process , it is dependent on the child
  调用方读取子进程的重定向流时依赖于该子进程。
• The caller waits on the read operation until the child writes to the stream or closes the stream
  调用方将等待读取操作，直到子进程写入流或关闭流为止。
• You can avoid deadlocks by evaluating dependencies between the caller and child process
  您可以通过计算调用方和子进程之间的依赖项从而避免出现死锁情况。
• Argument for a working directory , the manner of customizing the sub - process wasn t always that easy
  参数作为工作目录，所以用这种方法定制子进程比较困难。
• The child processes are started in the order specified by this list , and terminated in the reversed order
  子进程按列表顺序来启动，而终止时是相反的顺序。
• And the child process writes enough text to fill its error stream
  P . standarderror . readtoend ，并且子进程写入足够多的文本以填充错误流，就会产生死锁情况。
• Stream and the child process writing to that stream . these dependencies can result in deadlock conditions
  流的调用方及写入该流中的子进程之间引入一个依赖项。
• When the child process writes enough data to fill its redirected stream , it is dependent on the parent
  子进程写入足够多的数据以填充重定向流的时间依赖于父进程。
• The following c code , for example , shows how to read from a redirected stream and wait for the child process to exit
  例如，下面的c #代码演示如何读取重定向流并等待子进程退出。
• This part of the solution involves building a sub - process to handle the multiple requests for external information
  解决方案的这一部分建置了一个处理对外部资讯的多个请求的子进程。
