macOS how to get handle of a process?

[chidambaram]

hi everybody,

I am working in Mac machine(Version 10.4.7).

I have many pdf documents and indesign documents.

My requirement is to open a file(pdf or indesign, specified by user) and to trace the file to know when that file is closed by user. I need the time of file closed by user.

I open the user specified file using LSOpenFSRef().

How can i trace the file so that i can know when the file is closed?

Thanks in advance....
