From 9964a14579e5eef925aaa82facc4980f627802fe Mon Sep 17 00:00:00 2001 From: Zack Weinberg Date: Wed, 7 Feb 2018 18:42:04 -0500 Subject: Mechanically remove _IO_ name aliases for types and constants. This patch mechanically removes all remaining uses, and the definitions, of the following libio name aliases: name replaced with ---- ------------- _IO_FILE FILE _IO_fpos_t __fpos_t _IO_fpos64_t __fpos64_t _IO_size_t size_t _IO_ssize_t ssize_t or __ssize_t _IO_off_t off_t _IO_off64_t off64_t _IO_pid_t pid_t _IO_uid_t uid_t _IO_wint_t wint_t _IO_va_list va_list or __gnuc_va_list _IO_BUFSIZ BUFSIZ _IO_cookie_io_functions_t cookie_io_functions_t __io_read_fn cookie_read_function_t __io_write_fn cookie_write_function_t __io_seek_fn cookie_seek_function_t __io_close_fn cookie_close_function_t I used __fpos_t and __fpos64_t instead of fpos_t and fpos64_t because the definitions of fpos_t and fpos64_t depend on the largefile mode. I used __ssize_t and __gnuc_va_list in a handful of headers where namespace cleanliness might be relevant even though they're internal-use-only. In all other cases, I used the public-namespace name. There are a tiny handful of places where I left a use of 'struct _IO_FILE' alone, because it was being used together with 'struct _IO_FILE_plus' or 'struct _IO_FILE_complete' in the same arithmetic expression. Because this patch was almost entirely done with search and replace, I may have introduced indentation botches. I did proofread the diff, but I may have missed something. The ChangeLog below calls out all of the places where this was not a pure search-and-replace change. Installed stripped libraries and executables are unchanged by this patch, except that some assertions in vfscanf.c change line numbers. * libio/libio.h (_IO_FILE): Delete; all uses changed to FILE. (_IO_fpos_t): Delete; all uses changed to __fpos_t. (_IO_fpos64_t): Delete; all uses changed to __fpos64_t. (_IO_size_t): Delete; all uses changed to size_t. (_IO_ssize_t): Delete; all uses changed to ssize_t or __ssize_t. (_IO_off_t): Delete; all uses changed to off_t. (_IO_off64_t): Delete; all uses changed to off64_t. (_IO_pid_t): Delete; all uses changed to pid_t. (_IO_uid_t): Delete; all uses changed to uid_t. (_IO_wint_t): Delete; all uses changed to wint_t. (_IO_va_list): Delete; all uses changed to va_list or __gnuc_va_list. (_IO_BUFSIZ): Delete; all uses changed to BUFSIZ. (_IO_cookie_io_functions_t): Delete; all uses changed to cookie_io_functions_t. (__io_read_fn): Delete; all uses changed to cookie_read_function_t. (__io_write_fn): Delete; all uses changed to cookie_write_function_t. (__io_seek_fn): Delete; all uses changed to cookie_seek_function_t. (__io_close_fn): Delete: all uses changed to cookie_close_function_t. * libio/iofopncook.c: Remove unnecessary forward declarations. * libio/iolibio.h: Correct outdated commentary. * malloc/malloc.c (__malloc_stats): Remove unnecessary casts. * stdio-common/fxprintf.c (__fxprintf_nocancel): Remove unnecessary casts. * stdio-common/getline.c: Use _IO_getdelim directly. Don't redefine ssize_t. * stdio-common/printf_fp.c, stdio_common/printf_fphex.c * stdio-common/printf_size.c: Don't redefine size_t or FILE. Remove outdated comments. * stdio-common/vfscanf.c: Don't redefine va_list. --- libio/wstrops.c | 56 ++++++++++++++++++++++++++++---------------------------- 1 file changed, 28 insertions(+), 28 deletions(-) (limited to 'libio/wstrops.c') diff --git a/libio/wstrops.c b/libio/wstrops.c index a3374a7..36e8b20 100644 --- a/libio/wstrops.c +++ b/libio/wstrops.c @@ -32,19 +32,19 @@ #include void -_IO_wstr_init_static (_IO_FILE *fp, wchar_t *ptr, _IO_size_t size, +_IO_wstr_init_static (FILE *fp, wchar_t *ptr, size_t size, wchar_t *pstart) { wchar_t *end; if (size == 0) end = ptr + __wcslen (ptr); - else if ((_IO_size_t) ptr + size * sizeof (wchar_t) > (_IO_size_t) ptr) + else if ((size_t) ptr + size * sizeof (wchar_t) > (size_t) ptr) end = ptr + size; else /* Even for misaligned ptr make sure there is integral number of wide characters. */ - end = ptr + (-1 - (_IO_size_t) ptr) / sizeof (wchar_t); + end = ptr + (-1 - (size_t) ptr) / sizeof (wchar_t); _IO_wsetb (fp, ptr, end, 0); fp->_wide_data->_IO_write_base = ptr; @@ -66,11 +66,11 @@ _IO_wstr_init_static (_IO_FILE *fp, wchar_t *ptr, _IO_size_t size, (((_IO_strfile *) fp)->_s._allocate_buffer) = (_IO_alloc_type)0; } -_IO_wint_t -_IO_wstr_overflow (_IO_FILE *fp, _IO_wint_t c) +wint_t +_IO_wstr_overflow (FILE *fp, wint_t c) { int flush_only = c == WEOF; - _IO_size_t pos; + size_t pos; if (fp->_flags & _IO_NO_WRITES) return flush_only ?
