Re: [MI400] List APIs and addresses

["DennisLovelady" <dennis@xxxxxxxxxxxx>]

Hello, Tom:

Yes, a space is a space is a space.  I frequently use User Space objects as
receiver variable on APIs.   This is done by supplying the address of the
first byte of the *USRSPC as your receiver value.  As you wondered, this
works a treat because of SLS.

Phil:

I.e., what's the likelihood of an arbitrary API acting differently depending
on whether that first address points specifically to allocated memory or to
a *USRSPC object? At first glance, given single-level storage, etc., it
seems there'd be no difference (assuming proper authorities are granted,
etc.). But that gets to a level that's beyond me. Hence, the question to the
MI list.
