- ``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
