This directory contains 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 that the Google Cloud C++ client libraries do not follow Semantic Versioning.
The quickstart/ directory contains a minimal environment to get started using this client library in a larger project. The following "Hello World" program is used in this quickstart, and should give you a taste of this library.
For detailed instructions on how to build and install this library, see the top-level README.
#include "google/cloud/iot/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;
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;
