How do I handle timeouts and retries robustly?

Handling timeouts and retries in C++ applications is essential for building robust networked software. By implementing proper error handling and retry logic, you can ensure that your application can recover from transient failures and maintain a good user experience.

Implementing Timeout and Retry Logic

To handle timeouts and retries in C++, you can use a combination of standard library features and custom logic. Here's a simple example demonstrating how to implement this:

#include #include #include #include bool performOperation() { // Simulated operation that might fail return rand() % 2 == 0; } bool executeWithRetry(int maxRetries, int timeoutMs) { for (int attempt = 0; attempt < maxRetries; ++attempt) { if (performOperation()) { std::cout << "Operation succeeded!" << std::endl; return true; } else { std::cout << "Operation failed. Retry attempt " << (attempt + 1) << std::endl; // Simulate waiting for a timeout std::this_thread::sleep_for(std::chrono::milliseconds(timeoutMs)); } } std::cout << "All attempts failed." << std::endl; return false; } int main() { int maxRetries = 5; int timeoutMs = 1000; // 1 second executeWithRetry(maxRetries, timeoutMs); return 0; }
