Re: [Boost-users] [process] Determine if a process is still running?

Hi Boris, Thanks for getting back to me. We're currently using boost::process 0.31. I wasn't aware of 0.4, or any recent activity in boost::process. I'll keep that in mind the next time I have boost::process questions. As far as the create_snapshot proposal is concerned, that looks interesting. Unfortunately I need a solution very soon, so my guess is that I'll have to roll my own this time. Best, -- Allen Cronce On Sep 6, 2010, at 1:54 PM, Boris Schaeling wrote:

[...]I can see that boost::process supports obtaining a process ID. The question is can boost::process use this ID to determine if a given process, which was not launched as a child, is still running?

I assume you refer to Boost.Process 0.4 which has been released recently and is currently heavily discussed on the Boost developer's list.

There is a proposal at http://www.highscore.de/boost/gsoc2010/process/appendices.html how to create a snapshot of currently running processes. The function create_snapshot() wasn't finished in time though to ship it with 0.4. There were some more ideas to filter processes returned by create_snapshot() (eg. if you are only interested in processes owned by a certain user). But I think in general this kind of function could help you? You could then either iterate through the processes in the snapshot or filter with the process ID directly?
