Code:

Pnodo searchDocumentInPeople(Pnodo lista,int document)
{
    Pnodo aux;

    for(aux = lista;aux!=NULL; aux = aux->sig)
    {
        if(aux->info.document==document)
        {
           return aux;//return the direction of the node where it was found
          }
    }
    return NULL;//is not threre
