<p>
These bit values are intended for use in the
3rd parameter to the <a href="../c3ref/open.html">sqlite3_open_v2()</a> interface and
in the 4th parameter to the <a href="../c3ref/vfs.html#sqlite3vfsxopen">sqlite3_vfs.xOpen</a> method.</p>

<p>Only those flags marked as "Ok for sqlite3_open_v2()" may be
used as the third argument to the <a href="../c3ref/open.html">sqlite3_open_v2()</a> 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.</p>

<p>Note in particular that passing the SQLITE_OPEN_EXCLUSIVE flag into
<a href="../c3ref/open.html">sqlite3_open_v2()</a> does *not* cause the underlying database file
to be opened using O_EXCL.  Passing SQLITE_OPEN_EXCLUSIVE into
<a href="../c3ref/open.html">sqlite3_open_v2()</a> has historically be a no-op and might become an
error in future versions of SQLite.
