<a href="intro.html"><h2>Session Module C Interface</h2></a><h2>Configure global parameters</h2><blockquote><pre>int sqlite3session_config(int op, void *pArg);
</pre></blockquote><p>
The sqlite3session_config() interface is used to make global configuration
changes to the sessions module in order to tune it to the specific needs
of the application.</p>
<p>The sqlite3session_config() interface is not threadsafe. If it is invoked
while any other thread is inside any other sessions method then the
results are undefined. Furthermore, if it is invoked after any sessions
related objects have been created, the results are also undefined. </p>
<p>The first argument to the sqlite3session_config() function must be one
of the SQLITE_SESSION_CONFIG_XXX constants defined below. The
interpretation of the (void*) value passed as the second parameter and
the effect of calling this function depends on the value of the first
parameter.</p>
<p><dl>
<dt>SQLITE_SESSION_CONFIG_STRMSIZE<dd>
By default, the sessions module streaming interfaces attempt to input
and output data in approximately 1 KiB chunks. This operand may be used
to set and query the value of this configuration setting. The pointer
passed as the second argument must point to a value of type (int).
If this value is greater than 0, it is used as the new streaming data
chunk size for both input and output. Before returning, the (int) value
pointed to by pArg is set to the final value of the streaming interface
chunk size.
</dl></p>
<p>This function returns SQLITE_OK if successful, or an SQLite error code
otherwise.
