memalign() is obsolete according to its manpage. Replace memalign() with posix_memalign(). As a pointer is passed into posix_memalign(),initialize *map to NULL,to silence a warning about the function's return value being used as uninitialized (which is not valid anyway because the error is properly checked before p is returned).
