Virtual Memory Allocation And Paging
************************************

   This chapter describes how processes manage and use memory in a
system that uses the GNU C library.

   The GNU C Library has several functions for dynamically allocating
virtual memory in various ways.  They vary in generality and in
efficiency.  The library also provides functions for controlling paging
and allocation of real memory.
