<a href="intro.html"><h2>SQLite C Interface</h2></a><h2>Enable Or Disable Shared Pager Cache</h2><blockquote><pre>int sqlite3_enable_shared_cache(int);
</pre></blockquote><p>
This routine enables or disables the sharing of the database cache
and schema data structures between <a href="../c3ref/sqlite3.html">connections</a>
to the same database. Sharing is enabled if the argument is true
and disabled if the argument is false.</p>
<p>Cache sharing is enabled and disabled for an entire process.
This is a change as of SQLite version 3.5.0. In prior versions of SQLite,
sharing was enabled or disabled for each thread separately.</p>
<p>The cache sharing mode set by this interface effects all subsequent
calls to <a href="../c3ref/open.html">sqlite3_open()</a>, <a href="../c3ref/open.html">sqlite3_open_v2()</a>, and <a href="../c3ref/open.html">sqlite3_open16()</a>.
Existing database connections continue use the sharing mode
that was in effect at the time they were opened.</p>
<p>This routine returns <a href="../rescode.html#ok">SQLITE_OK</a> if shared cache was enabled or disabled
successfully. An <a href="../rescode.html">error code</a> is returned otherwise.</p>
<p>Shared cache is disabled by default. But this might change in
future releases of SQLite. Applications that care about shared
cache setting should set it explicitly.</p>
<p>This interface is threadsafe on processors where writing a
32-bit integer is atomic.</p>
<p>See Also: <a href="../sharedcache.html">SQLite Shared-Cache Mode</a>

<a href="objlist.html">Objects</a>,
