如何在Windows中启动子流程? [英] How can I start a sub-process in Windows?

问题描述

在POSIX中，有一个fork()函数来创建一个子进程.如何在Windows中实现fork()的功能?

In POSIX, there is the fork() function to create a sub-process. How can I achieve fork()'s functionality in Windows?

推荐答案

在Windows上没有直接等效的fork().

There is no direct equivalent of fork() on Windows.

CreateProcess() 是可用于创建新进程的本机函数(但同样，其语义与fork()的语义完全不同).

CreateProcess() is the native function that can be used to create a new process (but, again, the semantics are rather different to fork()'s).

换句话说，在Unix上，进程可以廉价地创建其自身的克隆.在Windows上没有便宜的方法可以做到这一点.

To put this another way, on Unix it is possible for a process to cheaply create a clone of itself. There is no inexpensive way to do this on Windows.

如果您不关心fork()的克隆方面，那么CreateProcess()应该就可以了.

If you don't care about the cloning aspect of fork(), then CreateProcess() should do just fine.
