Is there any way in cocoa to get some sort of notifications
when any process opens or closes any file? The reason i need
this is because i need to watch the system and do a certain
task every time a particular dylib is loaded by an application.
Alexander, I didn't see this thread until today and since it
wasn't really answered, I'll add my two cents.
What you probably want is the kqueue()/kevent() family of BSD
functions. It's not Cocoa, and programming it requires decoding
typically dense/terse UNIX APIs, but it allows you to receive
fine-grained notification of kernel events, including
notifications of when a particular file/directory is opened,
closed, or modified.
However, this still might not solve your problem. One of the
hallmarks of frameworks/dylibs is that their code is only loaded
once, and is then repeatedly mapped into the address space of
multiple processes. So watching to see when the file is opened
might not tell you if a process has loaded it, and it almost
certainly won't tell you what process did the loading.
