This function sends the received alarm information to the user application.

Parameters

Example

#include "pn_api_iod_alarm.h"
#include "pn_api_iod_callbacks.h"
#include "pn_api_iod_startup.h"
 
//Implement the callback function in the user application
void PN_APP_IOD_cbDevAlarm(
   PN_API_IOD_Handle_t *const pnHandle,
   PN_API_IOD_DevAlarmData_t *devAlarmData)
{...}
 
PN_API_IOD_Handle_t* pnHandle = NULL;
uint32_t status;
 
pnHandle = PN_API_IOD_new();
 
//Store callback functions implemented by the user application
PN_API_IOD_Callbacks_t callbacks = {
    .devAlarm = PN_APP_IOD_cbDevAlarm,
    ...}
 
//Register callback function
status = PN_API_IOD_registerCallbacks(pnHandle, &callbacks);
