Re: (semanticdb-directory-loaded-p default-directory) returns nil

Hi Eric,

I'd like to bump this, as well as add a new question.
Say that I store:

    (setq db (semanticdb-directory-loaded-p path))

Now `db` stores the database for all files in path. It happens
sometimes that I know for sure that one of these files was already
deleted. How can I update `db`, deleting the corresponding entry for
both for the current and future sessions?

regards,
Oleh
