wchar_t* wmemmove( wchar_t* dest, const wchar_t* src, std::size_t count );
Des copies count caractères de grande taille de l'objet pointé par src à l'objet pointé par dest. Les objets peuvent se chevaucher: la copie se passe comme si les personnages sont copiés vers un tableau de caractères temporaire, puis les personnages ont été copiés à partir du tableau de dest. Si les objets ne sont pas trivialement-copiable (scalaires, les tableaux de style C structs), le comportement est indéfini .
Original:
Copies count wide characters from the object pointed to by src to the object pointed to by dest. The objects may overlap: copying takes place as if the characters were copied to a temporary character array and then the characters were copied from the array to dest. If the objects are not trivially-copyable (scalars, arrays, C-style structs), the behavior is undefined.
