+<h2>Run-time Limits</h2>
+</div>
+<blockquote><pre>
+int sqlite3_limit(sqlite3*, int id, int newVal);
+</pre></blockquote>
+<p>
+This interface allows the size of various constructs to be limited
+on a connection by connection basis.  The first parameter is the
+<a href="../c3ref/sqlite3.html">database connection</a> whose limit is to be set or queried.  The
+second parameter is one of the <a href="../c3ref/c_limit_attached.html">limit categories</a> that define a
+class of constructs to be size limited.  The third parameter is the
+new limit for that construct.</p>
+
+<p>If the new limit is a negative number, the limit is unchanged.
+For each limit category SQLITE_LIMIT_<i>NAME</i> there is a
+<a href="../limits.html">hard upper bound</a>
+set at compile-time by a C preprocessor macro called
+<a href="../limits.html">SQLITE_MAX_<i>NAME</i></a>.
+(The "_LIMIT_" in the name is changed to "_MAX_".)
+Attempts to increase a limit above its hard upper bound are
+silently truncated to the hard upper bound.</p>
+
+<p>Regardless of whether or not the limit was changed, the
+<a href="../c3ref/limit.html">sqlite3_limit()</a> interface returns the prior value of the limit.
+Hence, to find the current value of a limit without changing it,
+simply invoke this interface with the third parameter set to -1.</p>
+
+<p>Run-time limits are intended for use in applications that manage
+both their own internal database and also databases that are controlled
+by untrusted external sources.  An example application might be a
+web browser that has its own databases for storing history and
+separate databases controlled by JavaScript applications downloaded
+off the Internet.  The internal databases can be given the
+large, default limits.  Databases managed by external sources can
+be given much smaller limits designed to prevent a denial of service
+attack.  Developers might also want to use the <a href="../c3ref/set_authorizer.html">sqlite3_set_authorizer()</a>
+interface to further control untrusted SQL.  The size of the database
+created by an untrusted script can be contained using the
+<a href="../pragma.html#pragma_max_page_count">max_page_count</a> <a href="../pragma.html#syntax">PRAGMA</a>.</p>
+
+<p>New run-time limit categories may be added in future releases.
