       #include <lastlog2.h>

       int ll2_import_lastlog (struct ll2_context *context, const char
       *lastlog_file, char **error);

DESCRIPTION         top

       Importing all entries from lastlog_file file (lastlog(8)) into
       lastlog2 database defined with context. If context is NULL, the
       default database, defined in LL2_DEFAULT_DATABASE, will be taken.

           char    *error = NULL;
           const   char *lastlog_path = "/var/log/lastlog";

           int ret = ll2_import_lastlog (NULL, lastlog_path, &error);

RETURN VALUE         top

       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.
