All addressable pages of the address space are locked.
Lock any future additions to the process virtual address space.
Note that does not imply
or can be used to unlock all or a portion of the address space locked with A single call to removes all locks from the process virtual
address space. An call results in only the specified pages being unlocked.
Regardless of how many times a process locks a page, a single or will unlock it.
When memory is shared by multiple processes and mlocks are applied to the same physical page by multiple processes, a page remains locked
until the last lock is removed from that page.
Locks and applied with are not inherited by a child process.
