Using mlockall() and munlockall()

The mlockall() and mlockall() interfaces are similar to mlock() and munlock(), but mlockall() and munlockall() operate on an entire address space. The mlockall() interface sets locks on all the pages in the address space. The munlockall() interface removes all the locks on all the pages in the address space, whether established by mlock() or mlockall().

For more information, see the mlockall(3C) and munlockall(3C) man pages.
