NAME

       pam_prompt, pam_vprompt - interface to conversation function

SYNOPSIS

       #include <security/pam_ext.h>

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

       void 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, response is set to point to a string returned from the conversation
       function. This string is allocated on heap and should be freed.
