Is there a way to get to know if a file is opened by a process?

Is there a way to get to know if a file is opened by a process?

In the standard C library, there isn't even such a thing as a "process".

Information about open files is operating system dependant. You will
need to ask your question in a newsgroup or mailing list specific to
your OS.

Note: your question is ambiguous and can be interpreted in at least
three ways. When you ask in the other newsgroup, you should be more
specific:

A) Is there at least one file that a specific process XYZ has open?
(For some particular definition of 'file' -- e.g., are you including
devices?)

B) Does specific process XYZ have specific file ABC open?

C) Is there some process which has specific file ABC open?


Note: if your operating system of interest is derived from Windows NT
then I suggest you check out the programs from sysinternals.com
(a wholely owned Microsoft division.)
