How to execute .load

I am writing some code and want to load the shared library Voodoo.

If tried this:
rc = sqlite3_exec(DB, "Voodoo", NULL, 0, &ErrMessage);

Well, that didn't do the job. Who has a idea to achieve this?

You mean:
rc = sqlite3_exec(DB,".load ./Voodoo", NULL, 0, &ErrMessage);

Which returns 1 which is not SQLite_OK and that it failed.

I suppose the load_extension() function is what you seek. s/Voodoo/load_extension('myVoodoExtLib')/

You may also need to enable extension loading from SQL.

Or, you could use the sqlite3_load_extension API.

BTW, the word "Extension" appears in the Permutated Index, a lot.

sqlite3_exec() expects SQL, not the CLI shell's metacommands.

Thank you for the information.
