GetODHandleDestructor

Retrieves a destructor for an ODHandle object.

ParamDestructorUPP GetODHandleDestructor ();

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 ODHandleDestructor (Environment* ev,
ODPtr* odHandle);

DISCUSSION

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

ODHandleDestructor (Environment* ev, ODPtr* odHandle)
{
   ODDisposeHandle (odHandle);
}

If you subclass ParameterSet, do not override this method.
