Defined in header <cwchar>
wchar_t* wmemcpy( 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. Si les objets se chevauchent, le comportement est indéfini. Si les objets ne sont pas trivialement copiable (scalaires, les tableaux C-compatibles structs), le comportement est indéfini .
Original:
Copies count wide characters from the object pointed to by src to the object pointed to by dest. If the objects overlap, the behavior is undefined. If the objects are not trivially copyable (scalars, arrays, C-compatible structs), the behavior is undefined.
