hal_io: Format system error messages in logs properly (!147) · Merge requests · D3TN / µD3TN

Felix Walter requested to merge hotfix/171-print-system-errors into master Dec 20, 2023

This simplifies the logging of system error messages by passing everything to a single fprintf call. The error message is obtained from strerror - as we guard everything via a semaphore this should not lead to any issue(s) we had in the past with it.

Fixes: #171 (closed)
