The POSIX version of `strerror_r()` returns 0 on success, and any other value indicates an error (Reference <http://pubs.opengroup.org/onlinepubs/9699919799/functions/strerror.html>). The function may return uninitialized memory if `std::snprintf()` fails. You may want to a version for Windows that calls `strerror_s()`. http://reviews.llvm.org/D20903 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
