Defined in header <memory>
void declare_no_pointers( char *p, std::size_t n )
(depuis C++11)
Informe le garbage collector ou détecteur de fuite que la zone de mémoire spécifiée (n octets commençant à l'octet pointé par p) ne contient pas de pointeurs traçables. Si une partie de la région est à l'intérieur d'un objet alloué, la région entière doit être contenue dans l'objet même .
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.
