Hi, not sure of the definitive answer but you can probably take a guess by
comparing with the Metal C library. By definition Metal C calls don't
require access to the unix kernel. In fact if you don't want to connect to
OMVS why not use Metal C anyway?
That's a no-brainer! For a simple example how about just being able to
use printf().

Subject: Which C library functions imply dub?
Sent by: IBM Mainframe Discussion List <[email protected]>
X-posted from a thread on MVS-OE
How would I determine which standard C library functions imply or cause a
dub? (Other than by trying them without an OMVS segment and seeing if they
blow up?) Is this documented somewhere? I guess another way of phrasing
the
question is "how would I determine which standard C library functions are
'UNIX functions'?"
Do most of them? Surely not strlen()? Does fopen()? Only if you reference
a
UNIX file as opposed to //DD:FOO?
