485 | Just because you have a perl object does not mean that the corresponding |
|
|
486 | C-level object still exists. If you try to access an object that has no |
|
|
487 | valid C counterpart anymore you get an exception at runtime. This method |
|
|
488 | can be used to test for existence of the C object part without causing an |
|
|
489 | exception. |
