In case it's any use, what we use on Linux is:
ftok(P) -- presumably you could use the sqlite file as the first
argument
shmget(P) -- using the id generated by ftok(), and using IPC_CREAT
if needed
shmat(P) and shmdt(P)
Our use case is different to sqlite and it's quite easy for us to
know when to create, initialise and finally shm_unlink() the memory
because we know in what order our processes start & stop. But
presumably you already have that issue in the mmap() version.
