Defined in header <cstring>
void* memmove( void* dest, const void* src, std::size_t count );
Cópias count personagens do objeto apontado por src ao objeto apontado por dest. Os objetos podem se sobrepor: copiar se passa como se os personagens foram copiadas para uma matriz caráter temporário e, em seguida, os personagens foram copiados da matriz para dest. Se os objetos não são trivialmente-copiável (escalares, matrizes de estilo C estruturas), o comportamento é indefinido.
Original:
Copies count 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.
