Библиотека отладчика MySQL
Библиотека отладчика, используемая MySQL была первоначально написана Фредом Фишом (Fred Fish). Она будет очень полезна, если Вы планируете отлаживать и/или добавлять функциональные возможности к СУБД MySQL.
Автор зачем-то приводит заголовок файла dbug.c из исходников пакета (вместе со всеми комментариями к нему). Приведу его и я, поскольку это может быть продиктовано какими-либо юридическими проблемами с копирайтом. Поскольку я не юрист, привожу этот заголовок без какого-либо перевода (во избежание ошибок или искажения смысла юридического документа при переводе).
