 22.4 Querying memory available resources
 ========================================
 
 The amount of memory available in the system and the way it is organized
 determines oftentimes the way programs can and have to work.  For
 functions like 'mmap' it is necessary to know about the size of
 individual memory pages and knowing how much memory is available enables
 a program to select appropriate sizes for, say, caches.  Before we get
 into these details a few words about memory subsystems in traditional
 Unix systems will be given.
