      Déclaré dans l'en-tête <cstdlib>
      void* calloc(std::size_t num, std::size_t size );
      Alloue de la mémoire pour un tableau d'objets num de size taille et l'initialise à zéro .
      Original:
      Allocates memory for an array of num objects of size size and zero-initializes it.

      Si l'allocation réussit, renvoie un pointeur vers le plus bas (premier) octet dans le bloc de mémoire alloué qui est correctement alignée pour n'importe quel type d'objet .
      Original:
      If allocation succeeds, returns a pointer to the lowest (first) byte in the allocated memory block that is suitably aligned for any object type.

      Si size est égal à zéro, le comportement est défini par l'implémentation (pointeur NULL peut être retourné, ou quelque pointeur non NULL peuvent être retournés qui ne peut pas être utilisé pour accéder au stockage)
      Original:
      If size is zero, the behavior is implementation defined (null pointer may be returned, or some non-null pointer may be returned that may not be used to access storage)

      [modifier]Notes

      En raison des exigences d'alignement, le nombre d'octets alloués n'est pas nécessairement égal à num*size .
      Original:
      Due to the alignment requirements, the number of allocated bytes is not necessarily equal to num*size.
