# DESCRIPTION

These bit values are intended for use in the 3rd parameter to the `sqlite3_open_v2`() interface and in the 4th parameter to the sqlite3_vfs.xOpen method.

Only those flags marked as "Ok for sqlite3_open_v2()" may be used as the third argument to the `sqlite3_open_v2`() interface. The other flags have historically been ignored by sqlite3_open_v2(), though future versions of SQLite might change so that an error is raised if any of the disallowed bits are passed into sqlite3_open_v2(). Applications should not depend on the historical behavior.

Note in particular that passing the SQLITE_OPEN_EXCLUSIVE flag into `sqlite3_open_v2`() does *not* cause the underlying database file to be opened using O_EXCL. Passing SQLITE_OPEN_EXCLUSIVE into `sqlite3_open_v2`() has historically be a no-op and might become an error in future versions of SQLite.
