void declare_no_pointers( char *p, std::size_t n )		(C + + 11以来)

ガベージコレクタまたはリークディテクタ、その指定されたメモリ領域（バイトから始まってnバイトpによって指される）がトレーサブルのポインタが含まれていませんが通知されます。地域のいずれかの部分が割り当てられたオブジェクトの範囲内であれば、地域全体が同じオブジェクトに含まれている必要があり.

Original:

Informs the garbage collector or leak detector that the specified memory region (n bytes beginning at the byte pointed to by p) contains no traceable pointers. If any part of the region is within an allocated object, the entire region must be contained in the same object.
