Global Function NutHeapRootRealloc()

* \brief Change the size of an allocated memory block. * * If more memory is requested than available at that block the data * is copied to a new, bigger block. * * \param block Points to a previously allocated memory block. If NULL, * then this call is equivalent to NutHeapRootAlloc(). * \param size The requested new size. If 0, then this call is * equivalent to NutHeapRootFree(). * * \return A pointer to the memory block on success or NULL on failures.
