ingres_pconnect -- 
     Open a persistent connection to an Ingres II database
    
Description
resource 
ingres_pconnect ( [string database [, string username [, string password]]] )
     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'.
