The documentation for the Unix type API's has this info but Scott Klement's web site has examples of using these API's (they're probably in the archives as well). Take a look at his IFS tutorial at http://www.scottklement.com/rpg/ifs.html.

Matt,

whats the process to determine the actual failure from the API ?
Can you point to a technique.

Thanks.

Are you calling the API to get the error number when it fails? That will
tell you what the problem is.

Subject: IFS problem with V5R4 upgrade

Has anyone seen this problem ?

I have an RPGLE program that reads a file on the IFS which is created by a
PC program (of mine).
This program has worked successfully for years over all OS/400 versions from
V5R1
Last week a Customer upgraded from V5R3 to V5R4 and the program now fails on
the open() of the IFS file (return code -1)
All other V5R4's including ours work OK.

The strange thing is that if I interactively debug the program - it works.

Any thoughts ?

Regards

Ian Patterson
