      Definido no cabeçalho <cstdlib>
      void free( void* ptr );
      Desaloca o espaço previamente alocado por malloc(), calloc() ou realloc(). Se ptr é ponteiro nulo, a função não faz nada.
      Original:
      Deallocates the space previously allocated by malloc(), calloc() or realloc(). If ptr is null-pointer, the function does nothing.

      O comportamento é indefinido se ptr não corresponde a um ponteiro retornado antes por malloc(), calloc() ou realloc(). Além disso, o comportamento é indefinido se a área de memória designado por ptr já foi desalocado, isto é, ou free() realloc() já foi chamado com ptr como argumento e nenhuma chamada para malloc(), calloc() ou realloc() resultou em um ponteiro igual a ptr depois.
      Original:
      The behavior is undefined if ptr does not match a pointer returned earlier by malloc(), calloc() or realloc(). Also, the behavior is undefined if the memory area referred to by ptr has already been deallocated, that is, free() or realloc() has already been called with ptr as the argument and no calls to malloc(), calloc() or realloc() resulted in a pointer equal to ptr afterwards.
