NAME
       pam_prompt, pam_vprompt - interface to conversation function

SYNOPSIS
       #include <security/pam_ext.h>

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

       int pam_vprompt(pam_handle_t *pamh, int style, char **response, const char *fmt,
                       va_list args);

DESCRIPTION
       The pam_prompt function constructs a message from the specified format string and arguments
       and passes it to the conversation function as set by the service. Upon successful return,

       allocated on heap and should be freed.

RETURN VALUES
       PAM_BUF_ERR
           Memory buffer error.

       PAM_CONV_ERR
           Conversation failure.

       PAM_SUCCESS

       PAM_SYSTEM_ERR
           System error.
