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.
