ingres_close
ingres_close
Description
bool ingres_close ([resource link])Returns TRUE on success, or FALSE on failure.
ingres_close() closes the connection to
the Ingres server that's associated with the specified link.
If the link parameter isn't
specified, the last opened link is used.
ingres_close() isn't usually necessary, as it
won't close persistent connections and all non-persistent connections
are automatically closed at the end of the script.
