I need to create a shared library to access an in memory DB. The DB is not huge, but big enough to make it cumbersome to carry around in every single process using the shared library. Luckily, it is pretty static information, so I don't need to worry much about synchronizing the data between... (12 Replies)

I am writing a shared library in Linux (but compatible with other UNIXes) and I want to allow multiple instances to share a piece of memory -- 1 byte is enough. What's the "best" way to do this? I want to optimize for speed and portability.
Obviously, I'll have to worry about mutual exclusion. (0 Replies)

Hi,
I wanted to know whether the POSIX message queues are statically allocated memory by the kernel based on the parameters specified in the open or as and when we send messages, memory are allocated?

If I have an AIX/FreeBSD/Solaris/HP-UX client that has an nfs share from a different system mounted on it, will the ACLs on the nfs share be processed properly?
My guess is that as... (2 Replies)

ipcrm [-M shmkey] [-m shmid] [-Q msgkey] [-q msqid] [-S semkey] [-s semid] ... DESCRIPTION

The following options are used to specify which IPC objects will be removed. Any number and combination of these options can be used: -M shmkey Mark the shared memory segment associated with key shmkey for removal. This marked segment will be destroyed after the last detach. -m shmid Mark the shared memory segment associated with id shmid for removal. This marked segment will be destroyed after the last detach. -Q msgkey Remove the message queue associated with key msgkey from the system. -q msqid Remove the message queue associated with the id msqid from the system. -S semkey Remove the semaphore set associated with key semkey from the system. -s semid Removes the semaphore set associated with id semid from the system. The identifiers and keys associated with these System V IPC objects can be determined by using ipcs(1) SEE ALSO
