Size the wide buffer based on the narrow buffer size. 2006-11-24 Jakub Jelinek [BZ #2337] * libio/libio.h (_IO_FLAGS2_USER_WBUF): Define. * libio/wgenops.c (_IO_wsetb, _IO_wdefault_finish): Test and set _IO_FLAGS2_USER_WBUF bit in _flags2 instead of _IO_USER_BUF bit in _flags. * libio/wstrops.c (_IO_wstr_overflow, enlarge_userbuf, _IO_wstr_finish): Likewise. * libio/wmemstream.c (open_wmemstream): Likewise. * libio/fileops.c (_IO_new_file_close_it): Call _IO_set[bgp] even for wide streams. --- libio/tst-setvbuf1.c | 39 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 libio/tst-setvbuf1.c (limited to 'libio/tst-setvbuf1.c') diff --git a/libio/tst-setvbuf1.c b/libio/tst-setvbuf1.c new file mode 100644 index 0000000..9222d40 --- /dev/null +++ b/libio/tst-setvbuf1.c @@ -0,0 +1,39 @@ +/* Dereived from the test case in BZ #2337. */ +#include +#include +#include +#include +#include +#include +#include +#include +#include + + +static char buf[512] __attribute__ ((aligned (4096))); + + +static int +do_test (void) +{ + setlocale (LC_ALL, "de_DE.UTF-8"); + + FILE *fp = fdopen (dup (STDOUT_FILENO), "a"); + if (fp == NULL) + error (EXIT_FAILURE, errno, "fdopen(,\"a\")"); + + setvbuf (fp, buf, _IOFBF, sizeof (buf)); + + /* fwprintf to unbuffered stream. */ + fwprintf (fp, L"hello.\n"); + + fclose (fp); + + /* touch my buffer */ + buf[45] = 'a'; + + return 0; +} + +#define TEST_FUNCTION do_test () +#include "../test-skeleton.c" -- cgit v1.1
