3.7.12.1 lbp_err lbp_scan_event_init(scan_thread_parameters para)
Initializes the scan event thread (the user must configure the parameters).
The scan event thread will detect the events of all segments. If there is an event
change in any segment, the thread will call the callback which the user completes the
parameter, para. The callback will get two inputs: one is the segment number and the
other one is the latest event. The period_100ms variable determines the sleep time
of a thread between two scanning operation.
The parameter is a structure in liblbpcu.h:
Returns 0 on success or -1 in the event of an error.
