GetODPtrDestructor

Retrieves a destructor for an ODPtr object.

ParamDestructorUPP GetODPtrDestructor ();

return value

A pointer to a destructor function that takes two parameters: an environment pointer and a pointer of type ODPtr*; the function returns no value. The function has the following form:

void ODPtrDestructor (Environment* ev,
ODPtr* odPtr);

DISCUSSION

You call this method to retrieve a destructor function suitable for an ODPtr object. The destructor function disposes of the ODPtr object, as shown in the following example:

ODPtrDestructor (Environment* ev, ODPtr* odPtr)
{
   ODDisposePtr(odPtr);
}

If you subclass ParameterSet, do not override this method.
