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.

       const char *name	(in)	      Name of desired option.

       const char *class (in)	      Class  of	 desired  option.   Null means

______________________________________________________________________________

DESCRIPTION
       This procedure is invoked to retrieve an	option from the	database asso-
       ciated  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.

KEYWORDS
