#########################
Introduction
============
The
memory management manager is ...
The directives provided by the memory management manager are:
- ``mlockall`` - Lock the Address Space of a Process
- ``munlockall`` - Unlock the Address Space of a Process
- ``mlock`` - Lock a Range of the Process Address Space
- ``munlock`` - Unlock a Range of the Process Address Space
- ``mmap`` - Map Process Addresses to a Memory Object
- ``munmap`` - Unmap Previously Mapped Addresses
- ``mprotect`` - Change Memory Protection
- ``msync`` - Memory Object Synchronization
- ``shm_open`` - Open a Shared Memory Object
- ``shm_unlink`` - Remove a Shared Memory Object
