|
<h2>Flags for sqlite3_deserialize()</h2>
|
|
</div>
|
|
<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 */
|
|
</pre></blockquote>
|
|
<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.
