How do I avoid exceptions in low-latency code?

In low-latency code, avoiding exceptions is crucial for maintaining performance. Exceptions can introduce unpredictable delays in execution time, which is unacceptable in latency-sensitive applications. Here are some strategies to minimize or eliminate exceptions in your C++ code:

• Use error codes: Instead of throwing exceptions, use return values or error codes to indicate failure. This allows you to handle errors without disrupting the flow of execution.
• Avoid dynamic memory allocation: Dynamic memory management can lead to exceptions and fragmentation. Use stack-allocated memory or pre-allocated pools to manage resources efficiently.
• Perform range checks: Use assertions and conditions to validate data before processing. This can help avoid situations that might lead to exceptions.
• Minimize state changes: Limit the number of state transitions in your code, which can help reduce the complexity and potential for errors.
• Static analysis: Utilize static analysis tools to identify potential exceptions and errors at compile-time rather than run-time.
