从另一个执行和捕获一个程序

问题描述

在C：

中的win32编程中在另一个win32程序中执行win32控制台程序的最佳方式是，启动执行的程序捕获输出？现在我把程序重定向输出到一个文件，但我相信我必须能够打开某种管道？

解决方案

使用 Win32 API启动子进程。

传递给它一个。

In win32 programming in C:

Whats the best way to execute a win32 console program within another win32 program, and have the program that started the execution capture the output? At the moment I made the program redirect output to a file, but I am sure I must be able to open some sort of pipe?

解决方案

Use the CreateProcess Win32 API to start the child process.

Pass to it a STARTUPINFO structure with hStdInput, hStdOutput and hStdError handles set to file handles you opened (either real files or memory mapped files should work). You don't need to specify all three, you can redirect only the ones you really need; most common case is hStdOutput.

If you want to communicate with the child process (through hStdInput), you need to wait for it to initialize by calling WaitForInputIdle.
