Hi all,

is there a way to find out if a file is opened by any process just by
filename?

Thanks in advice

Hi,
I don’t know in qnx but in unix

fuser -k -x -u the_file

From the command line:

sin file

or programatically use:

fsys_fdinfo()

(qnx 4) This works sometimes - depending on how many files are open and
how big Fsys’s name cache is. You will see “//1/…” for files whose
name Fsys has forgotten.
