     <function>ifx_connect</function> establishes a connection to an
     Informix server.  All of the arguments are optional, and if
     they're missing, defaults are taken from values supplied in <link
     linkend="configuration.file">configuration file</link>
     (ifx.default_host for the host (Informix libraries will use
     <envar>INFORMIXSERVER</envar> environment value if not defined),
     ifx.default_user for user, ifx.default_password for the password
     (none if not defined).
    </para>
    <para> 
     In case a second call is made to
     <function>ifx_connect</function> with the same arguments, no
     new link will be established, but instead, the link identifier of
     the already opened link will be returned.
    </para>
    <para> 
     The link to the server will be closed as soon as the execution of
     the script ends, unless it's closed earlier by explicitly calling
     <function>ifx_close</function>.
