tstUtf8.cpp@ 30552

Last change on this file since 30552 was 30320, checked in by vboxsync, 14 years ago
*: Replaced memchr(psz, '\0', cb) with RTStrEnd(psz, cb) and worked around memchr(_{RTSTR_MAX) issue in RTStrEnd. Here (linux.amd64 / glibc-2.10.1-r1) memchr fails for cb > ~(size_t)11. Since RTSTR_MAX is ~(size_t)0, this behavior breaks several IPRT string APIs.}
