Kernel isn't configured for semaphores

[alandao]

I tried running my toy program which uses semaphores and it gave back an invalid argument error which is unusual since my Ubuntu VM runs fine. When running ipcs, Bash states:

Kernel not configured for shared memory

Kernel not configured for semaphores

Kernel not configured for message queues

I'm guessing this part of the Bash on Windows system is incomplete?

@alandao - Your understanding is correct. Currently, support for these features is very limited to none. We will be tracking\prioritizing which features to light up next by looking at the feedback provided at the wpdev portal. So, please do provide your feedback there as well:

#16 is about the same problem.

System V shared memory and semaphore support is making its way to insider builds. Closing this out as this issue has bene open for a very long time.
