       This is a portable realloc() wrapper.

       In  general, this function will return an allocation at least sizeof(void*) bytes or bigger. If num_bytes
       is 0, then the allocation will be freed.

       If there was a failure to allocate num_bytes bytes, the process will be aborted.

       WARNING:
          This function will abort on failure to allocate memory.

       • mem: A memory region.

       • num_bytes: A size_t containing the new requested size.

       A pointer to a memory region which HASNOT been zeroed.
