openpam_nullconv(3) [freebsd man page]

OPENPAM_NULLCONV(3)					   BSD Library Functions Manual 				       OPENPAM_NULLCONV(3)

NAME
openpam_nullconv -- null conversation function LIBRARY
Pluggable Authentication Module Library (libpam, -lpam) SYNOPSIS
#include <sys/types.h> #include <security/pam_appl.h> #include <security/openpam.h> int openpam_nullconv(int n, const struct pam_message **msg, struct pam_response **resp, void *data); DESCRIPTION
The openpam_nullconv() function is a null conversation function suitable for applications that want to use PAM but don't support interactive dialog with the user. Such applications should set PAM_AUTHTOK to whatever authentication token they've obtained on their own before calling pam_authenticate(3) and / or pam_chauthtok(3), and their PAM configuration should specify the use_first_pass option for all modules that require access to the authentication token, to make sure they use PAM_AUTHTOK rather than try to query the user. RETURN VALUES
The openpam_nullconv() function returns one of the following values: [PAM_CONV_ERR] Conversation failure. SEE ALSO
openpam_ttyconv(3), pam(3), pam_authenticate(3), pam_chauthtok(3), pam_prompt(3), pam_set_item(3), pam_strerror(3), pam_vprompt(3) STANDARDS
The openpam_nullconv() function is an OpenPAM extension. AUTHORS
The openpam_nullconv() function and this manual page were developed for the FreeBSD Project by ThinkSec AS and Network Associates Laborato- ries, the Security Research Division of Network Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035 (``CBOSS''), as part of the DARPA CHATS research program. The OpenPAM library is maintained by Dag-Erling Smorgrav <des@des.no>. BSD

These functions are OpenPAM extensions to the PAM API. Those named pam_*() are, in the author's opinion, logical and necessary extensions to the standard API, while those named openpam_*() are either simple convenience functions, or functions intimately tied to OpenPAM implementa- tion details, and therefore not well suited to standardization.
