Threads in VMS

Hi All,

I want to know: Is threads are being supported in VMS and if yes where can I learn more about them.

If possible please provide me some links or programing examples through which I can learn how to use threads in VMS.

Re: Threads in VMS

Hi Ajaydec,

you might start with this manual, describing POSIX threads in OpenVMS:

Re: Threads in VMS


There are several thread-related concepts supported by OpenVMS. POSIX threads are supported, in several flavors and are fully documented (see the relevant documentation on the OpenVMS www site at http://www.hp.com/go/openvms ).

Internally, many OpenVMS systems facilities are designed around ASTs, which are a form of FIFO asynchronous event processing.

The programming concepts manual

is also always worth a read when contemplating particular ways of implementing things on VMS.

Re: Threads in VMS


from your Forum Profile:

I have assigned points to 59 of 116 responses to my questions.

Maybe you can find some time to do some assigning?


Mind, I do NOT say you necessarily need to give lots of points. It is fully up to _YOU_ to decide how many. If you consider an answer is not deserving any points, you can also assign 0 ( = zero ) points, and then that answer will no longer be counted as unassigned.
Consider, that every poster took at least the trouble of posting for you!

To easily find your streams with unassigned points, click your own name somewhere.
This will bring up your profile.
Near the bottom of that page, under the caption "My Question(s)" you will find "questions or topics with unassigned points " Clicking that will give all, and only, your questions that still have unassigned postings.
If you have closed some of those streams, you must "Reopen" them to "Submit points". (After which you can "Close" again)

Do not forget to explicitly activate "Submit points", or your effort gets lost again!!

Thanks on behalf of your Forum colleagues.

PS. - nothing personal in this. I try to post it to everyone with this kind of assignment ratio in this forum. If you have received a posting like this before - please do not take offence - none is intended!

PPS. - Zero points for this.


Have one on me.

Don't rust yours pelled jacker to fine doll missed aches.
