Tk_GetOption - retrieve an option from the option database
Tk_GetOption(tkwin, name, class)
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.
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 highestpriority
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
class, name, option, retrieve
