- Tk_Uid
- \fBTk_GetOption\fR(\fItkwin, name, class\fR)

- .SH DESCRIPTION
- .PP
- This procedure is invoked to retrieve an option from the database
- associated with \fItkwin\fR's main window. If there is an option
- for \fItkwin\fR that matches the given \fIname\fR or \fIclass\fR,
- then it is returned in the form of a Tk_Uid. If multiple options
- match \fIname\fR and \fIclass\fR, then the highest-priority one
- is returned. If no option matches, then NULL is returned.
- .PP
- \fBTk_GetOption\fR caches options related to \fItkwin\fR so that
- successive calls for the same \fItkwin\fR will execute much more
- quickly than successive calls for different windows.
