Hi all,
after some tests with the owcapi I found out, that for example the OW_get()
returns -1 with an errno of "2" in the following cases:
- invalid directory path, like "uncaxxched/"
- wrong CRC in unique-id of the device
- device is not reachable
did I made something wrong, or is there another method of determining a
reason for an error?
Thanks

use these before calling ow_init, then you will see the errors.
OW_set_error_print("0");
OW_set_error_level("6");
//OW_set_error_level=(0=default, 1=err_connect, 2=err_call, 3=err_data,
4=err_detail, 5=err_debug, 6=err_beyond)
//OW_set_error_print sets where the debug output should be directed.
0=mixed output, 1=syslog, 2=console.
It would be nice if the API had an error callback.
