Getting an EEXIST return code from iofunc_open_default(), and it’s
not listed as one of the return codes in the docs.
My question, “why?” How could the iofunc_open_default know which
files exist in my resource manager? 
Thanks,
-RK

O_CREAT | O_EXCL
It can deduce the existence by ‘dattr’ and ‘attr’ … you must be
specifying a NULL dattr, which is taken to mean that attr already
exists, which conflicts with this combination of ioflags …
A proper resmgr must pass dattr based on the result of the name
lookup: NULL if found, non-NULL for the directory to create in
if not found.
