# funclose(3)

close a Funtools data file

## NAME

**FunClose - close a Funtools data file**

## SYNOPSIS

```
  #include <funtools.h>
```

```
  void FunClose(Fun fun)
```

## DESCRIPTION

The ***FunClose()*** routine closes a previously-opened Funtools data file, freeing control structures. If a  Funtools reference handle was passed to the *FunOpen()* call for this file, and if copy mode also was specified for that file, then  *FunClose()* also will copy the remaining extensions from the input file to the output file (if the input file still is open).  Thus, we recommend always closing the output Funtools file **before** the input file.  (Alternatively, you can call *FunFlush()* explicitly).
