Function: semanticdb-current-database-list
semanticdb-current-database-list is a byte-compiled function defined
in db.el.gz.
Signature
(semanticdb-current-database-list &optional DIR)
Documentation
Return a list of databases associated with the current buffer.
If optional argument DIR is non-nil, then use DIR as the starting directory.
If this buffer has a database, but doesn't have a project associated
with it, return nil.
First, it checks semanticdb-project-root-functions, and if that
has no results, it checks semanticdb-project-roots. If that fails,
it returns the results of function semanticdb-current-database(var)/semanticdb-current-database(fun).
Always append semanticdb-project-system-databases if
semanticdb-search-system is non-nil.
