# ts\_setup(3)

find, open and configure a touch screen input device

## NAME

ts\_setup - find, open and configure a touch screen input device

## SYNOPSIS

```
#include <tslib.h>

struct tsdev *ts_setup(const char *dev_name, int nonblock);

```

## DESCRIPTION

**ts\_setup**() will try to find, open and configure the touch screen device. On success it allocates memory for a new touch screen device, opens and links the input event device to it and loads and initialises all modules configured in the tslib configuration file **TSLIB\_CONFFILE.**

If **dev\_name** is **NULL** **ts\_setup**() will use the device defined by the **TSLIB\_TSDEVICE** environment variable.

If **TSLIB\_TSDEVICE** is not defined **ts\_setup**() will try to use following devices:

/dev/input/ts,\
 /dev/input/touchscreen,\
 /dev/touchscreen/ucb1x00.

After that we ts\_setup() scans /dev/input/event\* for the first device with property INPUT\_PROP\_DIRECT.

## RETURN VALUE

A pointer to the opened **struct tsdev** is returned.
