Re: Max size for stream file APIs

Brad,
I think you are correct, as there is no "close64" or "read64" or "write64" as far as I can tell ... ;-)

So I'm playing around with this and downloading a test file (10GB).  It
appears all I really needed to update was stat and open to stat64 and
open64.

Is there any harm in leaving the read, write and close APIs as they are
now?  Most of my applications read and write in specified size chunks and
won't ever try to do more than so much data at a time.

Thanks!

As the others have said, many of the old IFS APIs, including stat() use
32-bit integers and are therefore limited to 2GB or 4GB file sizes.

Use stat64() instead, which uses 64-bit integers.

If you don't have prototypes you can find them here:

Just curious if anyone has run into an issue with the max size a stream
file can be when working with it through RPG and the IFS APIs.

I have someone with 25GB file and it's erroring out on the stat() call

to

check for it's existance (I don't have the RC right now).  Also, EDTF
reports an error as well "Object is too large to process."

Thanks.
