Handle arbitrary + multibyte strings, not just ASCII. + * include/stdio.h: Declare __fxprintf_nocancel. + * posix/getopt.c: When _LIBC is defined, define fprintf to + __fxprintf_nocancel, flockfile to _IO_flockfile, and funlockfile + to _IO_funlockfile. When neither _LIBC nor + _POSIX_THREAD_SAFE_FUNCTIONS is defined, define flockfile and + funlockfile as no-ops. + (_getopt_internal_r): Remove all internal #ifdef _LIBC blocks; + the standalone error-printing code can now be used for libc as + well. Add an flockfile/funlockfile pair around one case where + the error message is printed in several chunks. Don't use fputc. + * posix/tst-getopt-cancel.c: New test. + * posix/Makefile: Run it. + * posix/getopt.c (_getopt_internal_r): Don't increment d->optind a second time when reporting ambiguous -W options. |
