Simple test case. This application uses the C locale (by virtue of the fact that we did not use setlocale(), and evidenced by mb_cur_max of 1). On Linux, this correctly shows wctomb rejecting the conversion (0x100 is too big to fit in a 1-byte sequence) with EILSEQ, but newlib currently truncates the invalid wchar_t value to int and returns 1. #include <stdio.h> #include <stdlib.h> #include <errno.h> #include <wchar.h> #include <string.h> #include <limits.h> int main (int argc, char **argv) { wchar_t w = 0x100; char str[MB_LEN_MAX]; int i = wctomb(str, w); printf("mb_cur_max %zd, len %d, str[0] 0x%02hhx, errno %d\n", MB_CUR_MAX, i, str[0], errno); return 0; } -- Eric Blake -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
