Hello,

I wonder if the fuser utility coming with Cygwin is returning an error code that isn't in line with the IEEE specifaction. What is happening:

---

somogyib AT demuc12306 ~
$ fuser /cygdrive/f/Bazsi/cygwin/bin/bash; echo $?
/cygdrive/f/Bazsi/cygwin/bin/bash:  2708e
0
somogyib AT demuc12306 ~
$ fuser /cygdrive/f/Bazsi/cygwin/bin/awk; echo $?
1

---
 
So, the "bash" file is locked by one process and "awk" is by zero.

For both scenarios FreeBSD returns 0 which I assume to be correct. The IEEE standard says fuser should return non-zero value only when an error occured.
 
---

www.unix.org\single_unix_specification\susv3\utilities\fuser.html

EXIT STATUS
The following exit values shall be returned:
 0 
Successful completion. 
>0 
An error occurred.

---

A file being locked by one, two or ZERO process is all positive scenario so fuser should return 0. What's you opinion? Can this be fixed?

Cheers,
Balazs
