#include <sys/types.h>

int
pam_prompt(const pam_handle_t *pamh, int style, char **resp, const char *fmt, ...);

The () function constructs a message from the specified format string and arguments and passes it to the given PAM context's conversation function.

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 argument.

See pam_vprompt(3) for further details.

The pam_prompt() function returns one of the following values:

[PAM_SUCCESS]
Success.
[PAM_BUF_ERR]
Memory buffer error.
[PAM_CONV_ERR]
Conversation failure.
[PAM_SYSTEM_ERR]
System error.

pam(3), pam_error(3), pam_info(3), pam_strerror(3), pam_vprompt(3)

The pam_prompt() function is an OpenPAM extension.

The pam_prompt() function and this manual page were developed for the FreeBSD 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.

The OpenPAM library is maintained by Dag-Erling Smørgrav <des@des.no>.
