Description:

The MM library is a 2-layer abstraction library which simplifies the
usage of shared memory between forked (and this way strongly related)
processes under Unix platforms. On the first (lower) layer it hides
all platform dependent implementation details (allocation and locking)
when dealing with shared memory segments and on the second (higher)
layer it provides a high-level malloc(3)-style API for a convenient
and well known way to work with data-structures inside those shared
memory segments.
