DESCRIPTION

27       This procedure is invoked to retrieve an option from the database asso‐
28       ciated with tkwin's main window.  If there is an option for tkwin  that
29       matches  the  given name or class, then it is returned in the form of a
30       Tk_Uid.  If multiple options match name and class,  then  the  highest-
31       priority one is returned.  If no option matches, then NULL is returned.
32
33       Tk_GetOption  caches  options related to tkwin so that successive calls
34       for the same tkwin will execute much more quickly than successive calls
35       for different windows.
