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.
/dev/input/touchscreen,
/dev/touchscreen/ucb1x00.
RETURN VALUE¶
A pointer to the opened struct tsdev is returned.
