# ts\_close\_restricted(3)

use a custom function for closing the touchscreen's input device file

## NAME

ts\_close\_restricted - use a custom function for closing the touchscreen's input device file

## SYNOPSIS

```
#include <tslib.h>

void (*ts_close_restricted)(int fd, void *user_data);

```

## DESCRIPTION

**ts\_close\_restricted**() is useful if libts should not be run as root. If such a function is implemented by the user and assigned to the ts\_close\_restricted pointer, it will be called by ts\_close() instead of the close() system call directly.

It should obviously close the device with file descriptor **fd** while **user\_data** is currently unused.
