Pascal & pthreads

Is there an interface to pthreads from Pascal on I64.
Currently our application uses cma threads running on the Alpha and I would like to change this to the standard pthreads interface when I port to the Itanium (and also to run back on the Alpha so I only have to maintain one code set)
Thanks.

Re: Pascal & pthreads

I guess the issue is the definitions - a pascal version of pthread.h - is this correct?

it says you can call the pthreads library from other languages but you have to roll your own equivilent to pthread.h

Re: Pascal & pthreads

Do you know if anybody has created a pthreads definition file for VMS PASCAL - I don't know how to do it. Do you take the pthreads.h and convert it to PASCAL and work out how each type needs to passed?

Hi Richard,

It should be straightforward to construct the pthreads interface using similar conventions to those in SYS$LIBRARY:STARLET.PAS and SYS$LIBRARY:PASCAL$CMA_ROUTINES.PAS. Base it on the C headers and do a 1 for 1 conversion.

I'll have a look and see if we have any headers for pthread routines in house.

cheers

Brian

Richard, (and everybody else)

please do _NOT_ use plain e-mail addresses in your postings!

Mutilate them in a way that human readers will simply re-construct them, while making it hard for automatons to recognise!!
Mainly it is (alas!) a necessary means of self-protection.

Proost.

Have one on me.

Don't know how complete this. I've sanitised any potential condifdential info. The system using this code is live and quite likely somewhere near you.

Re: Pascal & pthreads

Thats exactly what I need, thanks - I'm curious now to know what is running it, any more clues?
