7 | * | ||
8 | * This file provides a really simple implementation of the system- | ||
9 | * dependent portion of the JPEG memory manager. This implementation | ||
10 | * assumes that no backing-store files are needed: all required space | ||
11 | * can be obtained from malloc(). | ||
12 | * This is very portable in the sense that it'll compile on almost anything, | ||
13 | * but you'd better have lots of main memory (or virtual memory) if you want | ||
14 | * to process big images. | ||
15 | * Note that the max_memory_to_use option is ignored by this implementation. | ||
