+    Os objetos desta classe são criados pelos métodos de construção <methodname>FFI::cdef</methodname>,
+    <methodname>FFI::load</methodname> ou <methodname>FFI::scope</methodname>. Variáveis ​​C definidas
+    são disponibilizadas como propriedades da instância FFI e funções C definidas são disponibilizadas
+    como métodos da instância FFI. Os tipos C declarados podem ser usados ​​para criar novas estruturas de dados C

+    A análise da definição FFI e o carregamento da biblioteca compartilhada podem levar um tempo significativo. Não é útil
+    fazer isso em cada solicitação HTTP em um ambiente Web. Entretanto, é possível pré-carregar definições e
+    bibliotecas FFI na inicialização do PHP e instanciar objetos FFI quando necessário. Os arquivos de cabeçalho
+    podem ser estendidos com definições especiais de <literal>FFI_SCOPE</literal> (por exemplo, <code>#define FFI_SCOPE "foo"</code>;
+    o escopo padrão é "C") e então carregados por <methodname>FFI::load</methodname> durante o pré-carregamento.
+    Isto leva à criação de uma ligação persistente, que estará disponível para todas as solicitações
+    seguintes através de <methodname>FFI::scope</methodname>.
+    Consulte o <link linkend="ffi.examples-complete">exemplo completo de PHP/FFI/pré-carregamento</link>
