- * These are interface routines to be placed between a program and the
- * system memory allocator.
- *
- * It forces well-defined semantics for several 'borderline' cases:
- *
- * malloc() of a 0 size object is guaranteed to return something
- * which is not 0, and can safely be freed (but not dereferenced)
- * free() accepts (silently) an 0 pointer
- * realloc of a 0 pointer is allowed, and is equiv. to malloc()
- * For the IBM/PC it forces no object > 64K; note that the size argument
- * to malloc/realloc is a 'long' to catch this condition
- *
- * The function pointer MMoutOfMemory() contains a vector to handle a
- * 'out-of-memory' error (which, by default, points at a simple wrap-up
- * and exit routine).
