Shared memory is a method of interprocess communication (IPC) where a single chunk of memory is shared between two or more processes. You can use shared memory APIs to set permissions on memory and to pass data between programs efficiently.

The following topics describe how you can use shared memory APIs when you develop POSIX compliant applications or port POSIX-based applications onto the Symbian platform.
