5 | * This file is part of the Independent JPEG Group's software. | ||
6 | * For conditions of distribution and use, see the accompanying README file. | ||
7 | * | ||
8 | * This include file defines the interface between the system-independent | ||
9 | * and system-dependent portions of the JPEG memory manager. No other | ||
10 | * modules need include it. (The system-independent portion is jmemmgr.c; | ||
11 | * there are several different versions of the system-dependent portion.) | ||
12 | * | ||
13 | * This file works as-is for the system-dependent memory managers supplied | ||
14 | * in the IJG distribution. You may need to modify it if you write a | ||
15 | * custom memory manager. If system-dependent changes are needed in | ||
16 | * this file, the best method is to #ifdef them based on a configuration | ||
17 | * symbol supplied in jconfig.h, as we have done with USE_MSDOS_MEMMGR | ||
18 | * and USE_MAC_MEMMGR. | ||
