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?
