[Pam-developers] Forwarding the password to the next PAM module?

My PAM module obtains the password from user with pam_get_authtok() and the pam_conv structure from pam_get_item(). Is it possible to forward this password (or modified one) to the next PAM module in the queue, so that it doesn't have to prompt the user for it again? If so, how can I do it?
