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?

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?
