Returns a Ingres II link resource on success, or FALSE on
failure.
See ingres_connect() for parameters details
and examples. There are only 2 differences between
ingres_pconnect() and
ingres_connect() : 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
(ingres_close() will not close links
established by ingres_pconnect()). This type
of link is therefore called 'persistent'.
