Re: Printing from ILE/C program running in QUSRWRK

Hi Jevgeni,

Is it possible that you are using IFS mode,  for example, with 
SYSIFCOPT(*IFSIO) on the compile command?  This error looks like the one 
you get when you specify an unknown IFS path -- and, yeah, *LIBL/EQRPT 
would certainly not be a valid IFS path.

The fopen() API and friends (fwrite, fputs, fgets, fclose, etc, etc) are 
designed to access the traditional library file system by default, but 
with SYSIFCOPT(*IFSIO) -- or similar options -- they switch to using IFS 
names.  IFS names don't allow library list.

Have you considered using _Ropen() and friends (record I/O functions) 
for a spooled file? It's been an awfully long time since I've generated 
a report from C, but I'm pretty sure that this is what I used. 
Something to think about...

-SK
