I dunno what you are going for - processes function pretty differently on those systems, so, no, there is not a cross-platform way to handle that case since process handling is inherently system specific.
If you are asking if there is some library to do this type of thing - maybe? I dunno. But, even if there is, the articles is talking about how such functionality can be implemented on Linux - which, if such a library existed, would be something that said library would implement.
