Hi Chris,

Out of curiosity, is there a difference between using fprintf and using perror for error handling? Is there an option we should opt for?

They have different roles.

The more familiar fprintf() allows you to print anything you want.

In contrast, perror() prints system-level error messages in a standard and consistent format. But it can only do that if the current value of errno reflects the most recent error, and not all functions set errno when detecting errors.
