5 * Revision 1.1 1996/11/10 21:23:14 morgan
11 * This file (via the use of macros) defines a wrapper for the malloc
12 * family of calls. It logs where the memory was requested and also
13 * where it was free()'d and keeps a list of currently requested memory.
15 * It is hoped that it will provide some help in locating memory leaks.
