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
function constructs a string from the
Fa fmt
and
Fa ap
arguments using
vsnprintf(3),
and passes it to the given PAM context's
conversation function.
The
Fa 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
Fa resp
argument.
The message and response should not exceed
PAM_MAX_MSG_SIZE
or
PAM_MAX_RESP_SIZE
respectively.
If they do, they may be truncated.
The
function and this manual page were developed for the
Fx Project by ThinkSec AS and Network Associates Laboratories, the
Security Research Division of Network Associates, Inc. under
DARPA/SPAWAR contract N66001-01-C-8035
(``CBOSS''
)
as part of the DARPA CHATS research program.
