<DL>
<P><DT>Tk_Window <B>tkwin</B> (in)<DD>
Token for window.
<P><DT>char <B>*name</B> (in)<DD>
Name of desired option.
<P><DT>char <B>*class</B> (in)<DD>

this option;  do lookup based on name only.
<P></DL>
<H3><A NAME="M5">DESCRIPTION</A></H3>
This procedure is invoked to retrieve an option from the database
associated with <I>tkwin</I>'s main window.  If there is an option
for <I>tkwin</I> that matches the given <I>name</I> or <I>class</I>,
then it is returned in the form of a <A HREF="../TkLib/GetUid.htm">Tk_Uid</A>.  If multiple options
match <I>name</I> and <I>class</I>, then the highest-priority one
is returned.  If no option matches, then NULL is returned.
<P>
<B>Tk_GetOption</B> caches options related to <I>tkwin</I> so that
successive calls for the same <I>tkwin</I> will execute much more
quickly than successive calls for different windows.
