[+2.9.1] Register a listener function that detects state changes of the OSDP device.

#include "BS_API.h"
 
int BS2_SetOsdpStandardDeviceStatusListener(void* context, OnOsdpStandardDeviceStatusChanged ptrOsdpStandardDeviceStatus);

• [In] context : Context
• [In] ptrOsdpStandardDeviceStatus : Callback function to receive changed device information when OSDP device state change is detected

If successfully done, BS_SDK_SUCCESS will be returned. If there is an error, the corresponding error code will be returned.

sample_bs2_setosdpstandarddevicestatuslistener.cpp

int sdkResult = BS2_SetOsdpStandardDeviceStatusListener(context_, fpOsdpStandardDeviceStatusChanged);
if (BS_SDK_SUCCESS != sdkResult)
	printf("BS2_SetOsdpStandardDeviceStatusListener call failed: %d", sdkResult);
 
return sdkResult;
