They are similar to the dlopen/dlerror/dlsym/dlclose methods under Posix. Check out those man pages. I also have documentation for them in my Python wrapper: http://apsw.googlecode.com/svn/publish/vfs.html#apsw.VFS.xDlClose > int (*xGetLastError)(sqlite3_vfs*, int, char *); > > (The last one seems a bit self evident, but there was no documentation on it, > either.) Don't bother implementing it. It isn't called anywhere. http://apsw.googlecode.com/svn/publish/vfs.html#apsw.VFS.xGetLastError Roger -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkv1qUQACgkQmOOfHg372QSmIACgk0o+05YBwg4fUdTO7LHgnvxM LoYAoM3crfCQ+Jz8YLw29W7ISzzCYKdS =Jzfn -----END PGP SIGNATURE----- _______________________________________________ sqlite-users mailing list [email protected] http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
