NAME
       Tk_GetOption - retrieve an option from the option database

SYNOPSIS
       #include <tk.h>

       Tk_Uid
       Tk_GetOption(tkwin, name, class)

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.
