# GetOption(3)

retrieve an option from the option database

## NAME

Tk\_GetOption - retrieve an option from the option database

## SYNOPSIS

```
#include <tk.h>

Tk_Uid
Tk_GetOption(tkwin, name, class)
```

## ARGUMENTS

Token for window. Name of desired option. 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.
