NAME

     openpam_ttyconv -- simple tty-based 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_ttyconv(int n, const struct pam_message **msg, struct pam_response **resp, void *data);

DESCRIPTION

     The openpam_ttyconv function is a standard conversation function suitable for use on TTY devices.	It should be adequate for the needs of
     most text-based interactive programs.

     The openpam_ttyconv function displays a prompt to, and reads in a password from /dev/tty. If this file is not accessible, openpam_ttyconv
     displays the prompt on the standard error output and reads from the standard input.

     The openpam_ttyconv function allows the application to specify a timeout for user input by setting the global integer variable
     openpam_ttyconv_timeout to the length of the timeout in seconds.

RETURN VALUES

     The openpam_ttyconv function returns one of the following values:

     [PAM_BUF_ERR]	 Memory buffer error.

     [PAM_CONV_ERR]	 Conversation failure.

     [PAM_SYSTEM_ERR]	 System error.

SEE ALSO

     getpass(3), openpam_nullconv(3), pam(3), pam_prompt(3), pam_strerror(3), pam_vprompt(3)

STANDARDS

     The openpam_ttyconv function is an OpenPAM extension.

DESCRIPTION

     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.
