SHMFIFO library provides an easy-to-use interface
to shared memory for programs where one process
needs to send blocks of data to other processes.
It was developed because pipe(2) and mkfifo(3)
have a very small buffer size (4k) and are
unsuitable for many applications. Shmfifo allows
you to put a block of data in shared memory, get
the oldest block of data from shared memory. It
also has the feature to share one instance of a
private data structure among all processes which
use the library.
