Use snprintf instead of sprintf to avoid buffer overflows Use snprintf in uu_lockerr instead of lots of hardcoded constants and not null-terminated strncpy Return "" for OK and "device in use" for INUSE, it allows simple strcpy(buf, uu_lockerr(retcode)) without testing for special OK case (NULL was there) and obtaining meaningful result for INUSE ("" was there) without special testing for it too.
