digitalmars.D.learn - How to use Linux message queues?

I've tried importing core.sys.posix.sys.msg however I get the 
error that is doesn't exist.

I sort of solved the problem with:

extern (C) int msgget ( key_t key, int msgflg );
extern (C) int msgsnd ( int msqid, msgbuf *msgp, int msgsz, int 
msgflg );

struct msgbuf {
     long mtype;         /* type of message */
     int a;
     int b;
};

though this is ugly and I don't have useful constants located in 
C headers. I'm wondering is there a better way to utilize Linux 
message queue IPC in D?

Yes, these are usually added when someone requires them.

Neven, if you're able, submitting a pull request to druntime of 
the complete module would be awesome. You can see how the others 
are structure here:

Ok, I've tried to make a module, though since I'm a D beginner 
(also a student who fiddles with D for Operating system classes) 
could you first feedback my code? I'm unsure in few parts which I 
commented on.

I spent some time reading manuals, reading through ipc.d for info 
how to do it, and reading msg.h in my distro (Linux Mint x86-64 
17) includes.

Not a bad start. A little tip, use c_long and c_ulong from 
core.stdc.config instead of long/ulong when interfacing with C. 
This is because its size changes when compiled on different 
architectures.

Incidentally, where are you studying? It would be nice to know 
where D is being taught.

I submitted a pull request.

D isn't officially taught and as far as I know only I use it on 
faculty. We were instructed we could use whatever language we 
like to code our exercises and later demonstrate its correctness.

My faculty is FER - http://www.fer.unizg.hr/en
Link is English version of faculty web page.
