     openpam_nullconv -- null conversation function

LIBRARY    [Toc]    [Back]

     PAM Library (libpam, -lpam)

SYNOPSIS    [Toc]    [Back]

     #include <sys/types.h>
     #include <security/pam_appl.h>

DESCRIPTION    [Toc]    [Back]

     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    [Toc]    [Back]

     The openpam_nullconv function returns one of the following values:

     [PAM_CONV_ERR]      Conversation failure.
