In July 2025, Yume Wikijp contributed to the cpprefjp/site repository by enhancing the documentation for the strtol function. Yume updated the reference to align with the original Qiita article title and removed author attribution, ensuring the documentation accurately mirrored the linked content. This work, carried out using Markdown and focused on documentation best practices, improved the accuracy and consistency of external references within the C standard library documentation. By reducing potential confusion for developers and strengthening the reliability of the resource, Yume’s contribution addressed a specific documentation gap, though the scope was limited to a single targeted feature update.
