I try to use the mmap system calls to remove the System V ipc i'm
using in my programs.

I found a HAS_SEMAPHORE flag in the mmap man pages and as 
the man pages lacks some explanantion I check in the source
code but I have been unable to find anything on this flags

what is it supposed to do ?
is it implemented in FreeBSD ?

Is there somewhere a tutorial that explain in depth the use
of these system calls ?

Thanks for your help,

Didier Derny
