RE: IFS file with read only attribute fails to unlink()

Scott;

I had missed the Qp0lSetAttr API while browsing the unix api list. I didn't
want to use the CHGATR and QCapCmd API but because of time constraints that
is what I did. I will put Qp0lSetAttr in my notes for that function and
upgrade it to the API later.

Thanks 
Duane Christen

Hi Duane,

I have an IFS file that has the read-only attribute set.

[SNIP]

I have attemted to use the chMod() function to change the read only 
attribute but it seems to only effect the authorities to the object/data 
and not the read only attribute.

Correct, chmod() is intended to be compatible with the Unix API for 
changing a file's mode. Since a file's mode isn't the same as it's 
attributes, chmod() won't help you.

The "read-only attribute" was designed to work like MS-DOS, and not like 
Unix.

Does anyone know the correct unix function to change the read only 
attribute of the correct mode(s) to use with chMod()?

Qp0lSetAttr() is the correct API to change the attribute.  It's not really 
a unix API, as it only exists on the iSeries (though it's still listed 
with the Unix APIs in the information center).

I find Qp0lSetAttr() to be rather awkward and difficult to code. There's 
also a CHGATR CL command that does the same thing, and you can call it via 
QCMDEXC -- much easier to code.
