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.
