+<blockquote><pre>
+#define SQLITE_DESERIALIZE_FREEONCLOSE 1 /* Call sqlite3_free() on close */
+#define SQLITE_DESERIALIZE_RESIZEABLE 2 /* Resize using sqlite3_realloc64() */
+#define SQLITE_DESERIALIZE_READONLY 4 /* Database is read-only */

+<p>
+The following are allowed values for 6th argument (the F argument) to
+the <a href="../c3ref/deserialize.html">sqlite3_deserialize(D,S,P,N,M,F)</a> interface.</p>
+
+<p>The SQLITE_DESERIALIZE_FREEONCLOSE means that the database serialization
+in the P argument is held in memory obtained from <a href="../c3ref/free.html">sqlite3_malloc64()</a>
+and that SQLite should take ownership of this memory and automatically
+free it when it has finished using it. Without this flag, the caller
+is responsible for freeing any dynamically allocated memory.</p>
+
+<p>The SQLITE_DESERIALIZE_RESIZEABLE flag means that SQLite is allowed to
+grow the size of the database using calls to <a href="../c3ref/free.html">sqlite3_realloc64()</a>. This
+flag should only be used if SQLITE_DESERIALIZE_FREEONCLOSE is also used.
+Without this flag, the deserialized database cannot increase in size beyond
+the number of bytes specified by the M parameter.</p>
+
+<p>The SQLITE_DESERIALIZE_READONLY flag means that the deserialized database
+should be treated as read-only.
