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 con-
     versation 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

     pam(3), pam_error(3), pam_info(3), pam_prompt(3), pam_strerror(3), pam_verror(3), pam_vinfo(3), vsnprintf(3)

STANDARDS

     The pam_vprompt function is an OpenPAM extension.
