&warn.experimental.func;
<para>
Returns a Ingres II link resource on success, or &false; on
failure.
</para>
<para>
<function>ingres_connect</function> opens a connection with the
Ingres database designated by <parameter>database</parameter>,
which follows the syntax
<parameter>[node_id::]dbname[/svr_class]</parameter>.
</para>
<para>
If some parameters are missing, <function>ingres_connect</function>
uses the values in &php.ini; for
<parameter>ingres.default_database</parameter>,
<parameter>ingres.default_user</parameter>, and
<parameter>ingres.default_password</parameter>.
</para>
<para>
The connection is closed when the script ends or when
<function>ingres_close</function> is called on this link.
</para>
<para>
All the other ingres functions use the last opened link as a
default, so you need to store the returned value only if you use
more than one link at a time.
