Para usar é o seguinte :
- Código:
//Por exemplo,você quer escrever um valor integer(4 Bytes) na memoria,usando Pointers :
Memory.WriteInteger(AddressPointer,OffSet,Value);
//Ou,sem Pointer
Memory.WriteInteger(Address,Value);
//Todas as funções Write(De escrever) retornam um valor Boolean(True,False) que se for verdadeiro a operação deu certou e se for Falso deu errado.
