NAMEopenpam_nullconv — null conversation function
LIBRARYPluggable Authentication Module Library (libpam, -lpam)
SYNOPSIS#include < sys/types.h>
#include < security/pam_appl.h>
#include < security/openpam.h>
openpam_nullconv( int n, const struct pam_message **msg, struct pam_response **resp, void *data);
DESCRIPTIONThe 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 VALUESThe openpam_nullconv() function returns one of the following values:
- [ PAM_CONV_ERR]
- Conversation failure.

STANDARDSThe openpam_nullconv() function is an OpenPAM extension.
