(windows) Go way to check if process PID still exists?

<p>I wanted to write a simple function that receives a PID number and then checks if a process is still running or not in windows.</p> <p>Is there a simple way to do this in Windows? some articles seem to give the idea that you need to read the entire process table (CreateToolhelp32Snapshot IIRC) but I thought it may be a simpler solution if you already have the process ID.</p> <hr/>**评论：**<br/><br/>distrus: <pre><p>You can try to use <a href="https://godoc.org/os#FindProcess" rel="nofollow">os.FindProcess</a>. I remember using it for this exact purpose, so I&#39;m pretty sure this should work. The caveat of this method is </p> <blockquote> <p>On Unix systems, FindProcess always succeeds and returns a Process for the given pid, regardless of whether the process exists.</p> </blockquote> <p>But since you&#39;re on Windows this shouldn&#39;t concern you too much.</p></pre>youguess: <pre><blockquote> <blockquote> <p>On Unix systems, FindProcess always succeeds and returns a Process for the given pid, regardless of whether the process exists.</p> </blockquote> </blockquote> <p>Why on Earth would they do that?
