| <h2 class="chapter">3 Virtual Memory Allocation And Paging</h2> |
| |
| <!-- %MENU% Allocating virtual memory and controlling paging --> |
| <p><a name="index-memory-allocation-231"></a><a name="index-storage-allocation-232"></a> |
| This chapter describes how processes manage and use memory in a system |
| that uses the GNU C library. |
| |
| <p>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. |
