No, there is no such function because
- you already know whether it's opened or not because you must store
the database connection handle obtained from the sqlite3_open* family of
functions - for example, initialize that variable to NULL before opening
the connection and after closing it, so your question becomes a simple
check against NULL on that variable
- it makes no sense to have such a function - the database connection
handle "belongs" to your application, not to the SQLite engine (that's
why you have to pass the handle as the first parameter to almost every
SQLite function)
If you're asking whether there is a function to check whether the *file*
which hosts the database structure and data is open or not, that depends
on the operating system you are using, and the answer should be
available in the operating system API documentation.
