The Question is:
Hi Wizard.
I'm working on a porting project of a Unix application to Alpha OpenVMS 7.1
workstation. I need to implement Unix IPC shared memory APIs like shmget(),
shmat(), shmctl().
I have found this can be accomplished with system services for
Global Sections, like SYS$CRMPSC, SYS$MGBLSC, SYS$DGBLSC.
Do you have some source code examples of such system services usage?
Thanks.
Angelo Di Bari
The Answer is :
Various calls such as mmap and related are available on current
OpenVMS versions.
Examples of the OpenVMS global section system services are located
at the main page of the OpenVMS Ask The Wizard area and at various
sites referenced in the OpenVMS FAQ. For a specific example at the
Ask The Wizard area, see the "Select a topic below to see Questions
Frequently Asked by Partners" section, and specifically the "Global
Sections(How to create and use.)" -- these topics are on the left
side of the Ask The Wizard main page.
Also please see topics (1661) and (2681).
