       The liblastlog2 library is part of the util-linux package since version 2.40. It can be downloaded from
       Linux Kernel Archive <https://www.kernel.org/pub/linux/utils/util-linux/>.

       Reads the first entry from database, defined in context, for user user. If context is NULL, the default
       database, defined in LL2_DEFAULT_DATABASE, will be taken.

           char    *error = NULL;
           const   char *user = "root";
           int64_t res_time;
           char    *res_tty = NULL;
           char    *res_rhost = NULL;
           char    *res_service = NULL;

           int ret = ll2_read_entry (NULL, user, &res_time, &res_tty, &res_rhost, &res_service, &error);

       For bug reports, use the issue tracker <https://github.com/util-linux/util-linux/issues>.

       Returns 0 on success, -ENOMEM or -1 on other failure. error contains an error string if the return value
       is -1. error is not guaranteed to contain an error string, could also be NULL. error should be freed by
       the caller. If lastlog2 database does not exist at all, the errno ENOENT is set and can be checked.

       The evaluated values are returned by ll_time, tty, rhost and pam_service.
