it is the first time I work with Cocoa and I wanted to know if there
is a way to launch a second application from the running one (and for
that I have found something) _and_ additionally being able to montior
this process/application in such a way to know exactly which file it
has opened for writing, which one he has created.
Creating a child process is pretty simple using NSTask (although, is
there a specific reason you want to use a child process and not a
thread?).
However, getting a list of the open files is not a trivial task
Just use the aforementioned simple NSTask to run 'lsof'. :-)
Or, if you know *where* the files will be opened, just watch that
directory with kqueue.
