Is there an example to check the registration status of an IoT edge device registered to an iot hub using device provisioning service in c?

As per above link, I understand that there is an api to check the device registration status in iot hub.

But is there an example which I can refer on how to use this api in c? I could not find anything in azure iot sdk c documentation or samples.

Hi @Arjun-Sivasree
You can get this kind of capability by using the PROV_DEVICE_CLIENT_REGISTER_STATUS_CALLBACK. Possible values returned from this callback can be found here:

azure-iot-sdk-c/provisioning_client/inc/azure_prov_client/prov_device_ll_client.h

Lines 41 to 47 in b576b03

	#define PROV_DEVICE_REG_STATUS_VALUES \
	PROV_DEVICE_REG_STATUS_CONNECTED, \
	PROV_DEVICE_REG_STATUS_REGISTERING, \
	PROV_DEVICE_REG_STATUS_ASSIGNING, \
	PROV_DEVICE_REG_STATUS_ASSIGNED, \
	PROV_DEVICE_REG_STATUS_ERROR, \
	PROV_DEVICE_REG_HUB_NOT_SPECIFIED

So while the status lookup isn't done synchronously by the user application, it is notified of the progress of the provisioning.

Let us know how else we can help here.
