- * Memory management routines.
- *
- * Set ralloc_aux to modify the memory allocation routine.
- * Set rnfree_aux to modify the memory de-allocation routine.
- * Set rpanic_aux to let the program react to memory failures.
- *
- * These routines work best as a *replacement* for malloc/free.
- *
- * The string_make() and string_free() routines handle dynamic strings.
- * A dynamic string is a string allocated at run-time, which should not
- * be modified once it has been created.
- *
- * Note the macros below which simplify the details of allocation,
- * deallocation, setting, clearing, casting, size extraction, etc.
- *
- * The macros MAKE/C_MAKE and KILL/C_KILL have a "procedural" metaphor,
- * and they actually modify their arguments.
- *
- * Note that, for some reason, some allocation macros may disallow
- * "stars" in type names, but you can use typedefs to circumvent
- * this. For example, instead of "type **p; MAKE(p,type*);" you
- * can use "typedef type *type_ptr; type_ptr *p; MAKE(p,type_ptr)".
- *
- * Note that it is assumed that "memset()" will function correctly,
- * in particular, that it returns its first argument.
