The Memory allocation module introduces a number of wrappers to basic memory management functions which allows to change the underlying memory allocator in a way that is transparent to the applications built on LibU. It is sufficient for an application to only use u_malloc/u_free and friends (which also include u_memdup, u_strndup and u_strdup from the Miscellaneous module) when carrying out memory allocation and deallocation operations. In case it'd be needed to change the underlying memory management facility with a custom one a call to u_memory_set_malloc and co. would be enough to fix it up, provided that the new memory management system has ISO C-like malloc(3) interfaces.
