#include <tk.h>

DESCRIPTION
This procedure is invoked to retrieve an option from the
database associated with tkwin's main window. If there is
an option for tkwin that matches the given name or class,
then it is returned in the form of a Tk_Uid. If multiple
options match name and class, then the highest-priority one
is returned. If no option matches, then NULL is returned.
Tk_GetOption caches options related to tkwin so that
successive calls for the same tkwin will execute much more
quickly than successive calls for different windows.
KEYWORDS
class, name, option, retrieve
