NAME    [Toc]    [Back]

     pam_get_authtok -- retrieve authentication token

LIBRARY    [Toc]    [Back]

     PAM Library (libpam, -lpam)

SYNOPSIS    [Toc]    [Back]

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

     pam_get_authtok(pam_handle_t *pamh, int item, const char **authtok,
         const char *prompt);

DESCRIPTION    [Toc]    [Back]

     The pam_get_authtok function returns the cached authentication token, or
     prompts the user if no token is currently cached.  Either way, a pointer
     to the authentication token is stored in the location pointed to by the
     authtok argument.

     The item argument must have one of the following values:

     PAM_AUTHTOK         Returns the current authentication token, or the new
                         token when changing authentication tokens.

     PAM_OLDAUTHTOK      Returns the previous authentication token when changing
 authentication tokens.

     The prompt argument specifies a prompt to use if no token is cached.  If
     appropriate, will be used.  If that item is also NULL, a hardcoded
     default prompt will be used.

     If item is set to PAM_AUTHTOK and there is a non-null PAM_OLDAUTHTOK
     item, pam_get_authtok will ask the user to confirm the new token by
     retyping it.  If there is a mismatch, pam_get_authtok will return

RETURN VALUES    [Toc]    [Back]

     The pam_get_authtok function returns one of the following values:

     [PAM_BUF_ERR]       Memory buffer error.

     [PAM_CONV_ERR]      Conversation failure.

     [PAM_SYSTEM_ERR]    System error.

     [PAM_TRY_AGAIN]     Try again.
