I should have been more explicit when I wrote this recommendation. Checking if `strerror_r` returns -1 is not portable. For example, OSX and FreeBSD return an error code from `strerror_r` without setting `errno`. The POSIX version should check for success by checking to see if `strerror_r` returns 0. If the function fails and the return value is not -1, assume that the return value is an error code. http://reviews.llvm.org/D20903 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
