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.

PAM_VPROMPT(3)						   BSD Library Functions Manual 					    PAM_VPROMPT(3)

NAME

     pam_vprompt -- call the conversation function

LIBRARY

     Pluggable Authentication Module Library (libpam, -lpam)

SYNOPSIS

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

     int
     pam_vprompt(const pam_handle_t *pamh, int style, char **resp, const char *fmt, va_list ap);

DESCRIPTION

     The pam_vprompt() function constructs a string from the fmt and ap arguments using vsnprintf(3), and passes it to the given PAM context's
     conversation function.

     The style argument specifies the type of interaction requested, and must be one of the following:

     PAM_PROMPT_ECHO_OFF
			 Display the message and obtain the user's response without displaying it.

     PAM_PROMPT_ECHO_ON  Display the message and obtain the user's response.

     PAM_ERROR_MSG	 Display the message as an error message, and do not wait for a response.

     PAM_TEXT_INFO	 Display the message as an informational message, and do not wait for a response.

     A pointer to the response, or NULL if the conversation function did not return one, is stored in the location pointed to by the resp argu-
     ment.

     The message and response should not exceed PAM_MAX_MSG_SIZE or PAM_MAX_RESP_SIZE, respectively.  If they do, they may be truncated.

RETURN VALUES

     The pam_vprompt() 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

STANDARDS

     The pam_vprompt() function is an OpenPAM extension.
