Re: List APIs and addresses

From: <thomas@inorbit.com>

. Here's the scenario:

Suppose a list API named QabcListAPI returns the list into a program
variable. (This differs from various list APIs that return lists into user
spaces.)

Q1. Should I be able to create a *USRSPC of some large size, initialize the
space to a value such as X'00' at creation, retrieve a pointer to it and then
pass the pointer to QabcListAPI as if it were the address of a program
variable? After the API call, I could then access the list data via a based
variable in multiple other programs.

===> YES (depending a little bit on how you code QabcListAPI - you can pass a
variable or a
pointer to a variable)


Q2: If that should work at all, would security level 50 cause issues?

===>No problem with level 50 if the space is in the user domain.


I just whipped up a little test program to try out the above. Works fine (I'm
at V4R5, level 50).
