NAME
     Tk_GetOption - retrieve an option from the option database

SYNOPSIS
     #include <tk.h>

     Tk_Uid
     Tk_GetOption(tkwin, name, class)

ARGUMENTS
     Tk_Window   tkwin    (in)      Token for window.

     char        *name    (in)      Name of desired option.

     char        *class   (in)      Class of desired option.  Null means there
                                    is no class for this option;  do lookup
                                    based on name only.


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.
