Shared Memory

Description

The Shared Memory component provides cross-platform access to shared memory.

This module makes it simple to employ shared memory in Qt applications. Shared memory can be used for high-speed inter-process communication. It provides a portable, platform-independent class API to the shared memory mechanism of the underlying operating system, and implements a locking mechanism to ensure safe access from multiple concurrent processes.

This Qt Solutions component is for Qt 3. For Qt 4 Solutions, please visit http://www.trolltech.com/products/solutions/catalog/4/.
