IPC::MMA is Copyright (C) 2008-2010, Craig MacKenna DESCRIPTION IPC::MMA allows data to be shared among related Unix/Linux processes in a straightforward way. It provides methods to create and destroy shared memory segments and to create, access, and maintain data structures within segments. Perl scalars, arrays, and hashes can be stored in shared memory. There are six possible kinds of arrays: general-purpose scalars, signed or unsigned integers, floating-point numbers, fixed-length strings/records, and single-bit booleans.

See http://www.ossp.org/pkg/lib/mm/ for more about mm. Experienced users may prefer to install mm from a different source: debian/ubuntu: $ sudo apt-get install libmm-dev FreeBSD ports: $ cd ports/devel/mm # (wherever ports lives) $ sudo make $ sudo make install INSTALLATION Your computer needs to have the mm library before you can use IPC::MMA. Many Unix/Linux systems include this library. If you need to download and install mm, see the preceding section. The easy way to install IPC::MMA: $ perl -MCPAN -e "install IPC::MMA" The classic way: Choose a directory to use for installing. Move/download the distribution file IPC-MMA-n.nn.tar.gz into it cd into it $ tar -xf IPC-MMA-n.nn.tar.gz This will produce a new directory IPC-MMA-n.nn. $ cd IPC-MMA-n.nn $ perl Makefile.PL $ make $ make test Assuming those steps don't show any problems: $ sudo make install (or just make install if you're superuser) Either of the above alternatives should install IPC::MMA into the Perl library. See the POD documentation for further details. Once the module is installed, you should be able to read the documentation by typing the following from the command-line: $ perldoc IPC::MMA Or if your man system is configured in a compatible way: $ man IPC::MMA NOTES This module requires perl 5.6 or later. The initial use of the array functions of this module was to track related-file accesses on our Apache web server, and thus optimize use of the HTTP keep-alive feature. Watch CPAN for this module in the future (its working name is Apache2::CloseKeepAlive). Craig MacKenna Jan 4 2010
