Cloud IoT API C++ Client Library

An idiomatic C++ client library for the Cloud IoT API, a service to register and manage IoT (Internet of Things) devices that connect to the Google Cloud Platform.

While this library is GA, please note Google Cloud C++ client libraries do not follow Semantic Versioning.

Quickstart

The following shows the code that you'll run in the google/cloud/iot/quickstart/ directory, which should give you a taste of the Cloud IoT API C++ client library API.

#include "google/cloud/iot/v1/device_manager_client.h"
#include "google/cloud/project.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 3) {
    std::cerr << "Usage: " << argv[0] << " project-id location-id\n";
    return 1;
  }

  namespace iot = ::google::cloud::iot_v1;
  auto client = iot::DeviceManagerClient(iot::MakeDeviceManagerConnection());

  auto const project = google::cloud::Project(argv[1]);
  auto const parent = project.FullName() + "/locations/" + argv[2];
  for (auto dr : client.ListDeviceRegistries(parent)) {
    if (!dr) throw std::move(dr).status();
    std::cout << dr->DebugString() << "\n";
  }

  return 0;
} catch (google::cloud::Status const& status) {
  std::cerr << "google::cloud::Status thrown: " << status << "\n";
  return 1;
}

Main classes

The main class in this library is iot_v1::DeviceManagerClient. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock iot_v1::DeviceManagerClient when testing your application.
