&warn.experimental.func;
<para>
Returns a Ingres II link resource on success, or &false; on
failure.
</para>
<para>
See <function>ingres_connect</function> for parameters details
and examples. There are only 2 differences between
<function>ingres_pconnect</function> and
<function>ingres_connect</function> : First, when connecting, the
function will first try to find a (persistent) link that's
already opened with the same parameters. If one is found, an
identifier for it will be returned instead of opening a new
connection. Second, the connection to the Ingres server will not
be closed when the execution of the script ends. Instead, the
link will remain open for future use
(<function>ingres_close</function> will not close links
established by <function>ingres_pconnect</function>). This type
of link is therefore called 'persistent'.
</para>
<para> See also
<function>ingres_connect</function> and
<function>ingres_close</function>.
