IPC::MMA provides an interface to Ralf Engelschall's mm library, allowing memory to be shared between multiple processes in a relatively convenient way. IPC::MMA is a superset of Arthur Choung's IPC::MM module, adding arrays and allowing any Perl scalar to be used as a hash/BTree key rather than just C strings. IPC::MMA hashes are like IPC::MM BTrees in that they return keys in sorted order ineach, keys, and next operations. An IPC::MMA array can store data in any of six ways, including general-purpose scalars, signed or unsigned integers, floating-point numbers, fixed-length strings/records, and booleans at one bit per array element.
