Hi,
I am working on Linux, just i wanted to clear my doubts.

What is the difference between posix ipc and system v ipc in linux?

What are the advantages of POSIX IPC over system v IPCs.

Where they preferred actually?
 

System V is used from Old version of Unix system operating system API. POSIX (Portable Operating System Interface Unix) is meant to be new portable implementation of API created after during Unix War. POSIX is supposed to be thread safe and is relatively advanced but still System V is used widely.

If your project is new development and compatibility with old software is not needed use POSIX.
