DESCRIPTION

31       The list of extension records at the specified offset in the specified
32       widget_class will be searched for a match on the specified type, a ver‐
33       sion greater than or equal to the specified version, and a record size
34       greater than or equal the specified record_size if it is nonzero.
35       XtGetClassExtension returns a pointer to a matching extension record or
36       NULL if no match is found. The returned extension record is owned by
37       the widget class and must not be modified or freed by the caller,
38       except possibly to be modified by the widget class owner.
