* The QSE_XTN() macro is a convenience macro to retrieve the pointer to
* extension space located at the end of an object. The type of the object
* should be known in advance for it to work properly.

*
* however, most object types provide a specialized function to retreive

* the corresponding function is qse_sample_getmmgr().
*
* Use the specialized function over QSE_XTN() wherever possible.
