Hi Alex,



Take a look here:

You also need the FORK for Windows ("winfork") to run it:

I am not sure how well it runs though. There have been some changes in (source), for example. On my on machines at home I do not have Windows anymore, but I can verify it next week at my work.

Actualy semaphore is not that different to simmulate if its not in the OS your

worknig with... The only thing you need is "1 common share", that could be also

a file a named-pipe or anything that alows you to read/write too..

I try use (winfork) in example for (semaphore) from manual - it is not work :-(

(prodcons) can't work because of (wait-pid) can't work in Win(see manual). :-(



Resume: I have function (semaphore) in Win, but I can't use it.

What is wrong?

I use newLISP v.8.9.0 on Win32 MinGW now

Indeed, there is no (wait-pid) in Windows.



Therefore you have to use my version of 'prodcons' which I mentioned earlier:

As you can see, there is no (wait-pid) in there.
