Another idiom I often use is separating resource allocation from actual computation:

int foobar1 (some_type * some_pointer)
{
  int result = foo (some_pointer);
  if (result < 0)
    result = bar (some_pointer, result);
  return result;
}

int foobar()
{
  int result = -1;
  void * some_pointer = malloc (sizeof (some_type));
  if (some_pointer) {
    result = foobar1 (some_pointer);
    free (some_pointer);
  }
  return result;
}
