Forging a RADIUS request within a module

Hi all, During authentication process, I need to send an Accounting-Start to a network equipment when the authentication is successful (when processing the Access-Request), before sending the Access-Accept back. Is it possible to create the Accounting-Request from inside a module and "post it" as an event, to let FreeRADIUS core manage processing/sending? If not, I will have to trigger an external radiusclient to do the job. Thanks for your answers. Geoff.
