The Language Environment Vendor Interfaces (SA22-7568-09) mentions the

Beware that the "some restrictions" can be quite significant in practice.
Many of the C/C++ library routines you might expect to use just don't work
in that environment.
What about just pure C/C++ code without calling LE library routines or
C-Runtime library routines and assuming that malloc/free and new/delete
eventually invokes the STORAGE OBTAIN/DELETE provided by the substitute
service routines?
What about C++ STL?
Thanks.
Hi Sam,
We offer exactly that environment with the Dignus runtime.
You can replace our memory routines...
We have customers doing exactly what you're talking about.
With the Dignus runtime, you can replace the memory allocation/freeing
to do something appropriate for your runtime environment... and, you
can then either avoid I/O, or replace it...
This gives you the ability to do many things in a rather restricted
environment.
Also - using our "Direct CALL" environment, you can establish the C/C++
runtime
ahead-of-time to avoid that overhead, etc... (assuming you don't want
to do that
every time you get into SRB mode, etc....)
