Re: How to know a file is busy(read/write)?

What are you trying to do with the file?

Even if there were a perfect API to provide detailed status of a file, 
that status can change between the time you check and act on the file.

In most situations I encounter the real solution is to act on the file 
and then handle the error case at that time.
