<blockquote><pre>
int sqlite3_vtab_config(sqlite3*, int op, ...);

<p>
This function may be called by either the <a href="../vtab.html#xconnect">xConnect</a> or <a href="../vtab.html#xcreate">xCreate</a> method
of a <a href="../vtab.html">virtual table</a> implementation to configure
various facets of the virtual table interface.</p>
<p>If this interface is invoked outside the context of an xConnect or
xCreate virtual table method then the behavior is undefined.</p>
<p>In the call sqlite3_vtab_config(D,C,...) the D parameter is the
<a href="../c3ref/sqlite3.html">database connection</a> in which the virtual table is being created and
which is passed in as the first argument to the <a href="../vtab.html#xconnect">xConnect</a> or <a href="../vtab.html#xcreate">xCreate</a>
method that is invoking sqlite3_vtab_config(). The C parameter is one
of the <a href="../c3ref/c_vtab_constraint_support.html">virtual table configuration options</a>. The presence and meaning
of parameters after C depend on which <a href="../c3ref/c_vtab_constraint_support.html">virtual table configuration option</a>
is used.
