# Cloud Tasks API C++ Client Library

This directory contains an idiomatic C++ client library for
[Cloud Tasks API][cloud-service-root], a service that manages the execution of
large numbers of distributed requests.

While this library is **GA**, please note that the Google Cloud C++ client
libraries do **not** follow [Semantic Versioning](https://semver.org/).

## Quickstart

The [quickstart/](quickstart/README.md) 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](/README.md#building-and-installing).

```cc
#include "google/cloud/tasks/v2/cloud_tasks_client.h"
#include "google/cloud/location.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;
  }

  auto const location = google::cloud::Location(argv[1], argv[2]);

  namespace tasks = ::google::cloud::tasks_v2;
  auto client = tasks::CloudTasksClient(tasks::MakeCloudTasksConnection());

  for (auto queue : client.ListQueues(location.FullName())) {
    if (!queue) throw std::move(queue).status();
    std::cout << queue->DebugString() << "\n";
  }

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