XtGetClassExtension - locate a class extension record
#include <X11/Intrinsic.h>
XtPointer XtGetClassExtension(WidgetClass object_class, Cardinal byte_offset, XrmQuark type, long version, Cardinal record_size);
The list of extension records at the specified offset in the specified widget_class will be searched for a match on the specified type, a version greater than or equal to the specified version, and a record size greater than or equal the specified record_size if it is nonzero. XtGetClassExtension returns a pointer to a matching extension record or NULL if no match is found. The returned extension record is owned by the widget class and must not be modified or freed by the caller, except possibly to be modified by the widget class owner.
