      Definido no cabeçalho <setjmp.h>
      void longjmp( jmp_buf env, int status );
      Carrega o env contexto de execução salvo por uma chamada anterior a setjmp. Esta função não retorna. O controle é transferido para o local chamado do setjmp macro que criou env. setjmp que retorna o valor, passado como o status.
      Original:
      Loads the execution context env saved by a previous call to setjmp. This function does not return. Control is transferred to the call site of the macro setjmp that set up env. That setjmp then returns the value, passed as the status.

      Se a função que chamou setjmp foi encerrado, o comportamento é indefinido (em outras palavras, apenas saltos longos até a pilha de chamadas são permitidos)
      Original:
      If the function that called setjmp has exited, the behavior is undefined (in other words, only long jumps up the call stack are allowed)

      Não destruidores para objetos automáticos são chamados. Se a substituição de longjmp com throw e setjmp com catch iria executar um destrutor não-trivial para qualquer objeto automático, o comportamento de tais longjmp é indefinido.
      Original:
      No destructors for automatic objects are called. If replacing of longjmp with throw and setjmp with catch would execute a non-trivial destructor for any automatic object, the behavior of such longjmp is undefined.
