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 suc
cessive calls for the same tkwin will execute much more
quickly than successive calls for different windows.
