From feb3c934355a9a2331cdfeb7ab6351fd4856164f Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 9 Dec 1996 03:15:25 +0000 Subject: update from main archive 961208 Mon Dec 9 03:39:30 1996 Ulrich Drepper * config.make.in (defines): Add @USE_NEW_MALLOC@. * Makefile.in: Define USE_NEW_MALLOC to -DUSE_NEW_MALLOC if we use the new malloc. * malloc.h: Use either or depending on USE_NEW_MALLOC. Fix some more POSIX.1 problems. * libio/fileops.c (_IO_file_underflow): Set errno to EBADF if used on a write-only stream. (_IO_file_overflow): Set errno to EBADF if used on a read-only stream. (_IO_file_seekoff): POSIX.1 requires that fseek() after an fflush() call really positions the file offset to the correct position and no read-ahead happens. * locale/C-monetary.c: Set mon_grouping file to "" and "\377" to pass POSIX test suite. * stdio-common/vfprintf.c: Handle empty string as grouping command correctly. * stdlib/grouping.h: Likewise. * misc/syslog.c: Case first argument of __libc_cleanup_region_start. * signal/sigsetops.h: Update copyright. Don't include ansidecl.h. * stdio-common/printf_fp.c: Update copyright. Sun Dec 8 16:39:28 1996 Andreas Jaeger * time/Makefile: Compile ap.c with NO_MCHECK flag if new-malloc used (not otherwise). * misc/syslog.c (vsyslog): Cast argument to __libc_cleanup_region to get Hurd macros right. --- libio/fileops.c | 17 ++++++++++++++--- 1 file changed, 14 insertions(+), 3 deletions(-) (limited to 'libio/fileops.c') diff --git a/libio/fileops.c b/libio/fileops.c index ce0e2bb524..b5026e167a 100644 --- a/libio/fileops.c +++ b/libio/fileops.c @@ -269,7 +269,10 @@ DEFUN(_IO_file_underflow, (fp), #endif if (fp->_flags & _IO_NO_READS) - return EOF; + { + __set_errno (EBADF); + return EOF; + } if (fp->_IO_read_ptr < fp->_IO_read_end) return *(unsigned char*)fp->_IO_read_ptr; @@ -308,7 +311,10 @@ DEFUN(_IO_file_overflow, (f, ch), register _IO_FILE* f AND int ch) { if (f->_flags & _IO_NO_WRITES) /* SET ERROR */ - return EOF; + { + __set_errno (EBADF); + return EOF; + } /* If currently reading or no buffer allocated. */ if ((f->_flags & _IO_CURRENTLY_PUTTING) == 0) { @@ -387,6 +393,10 @@ DEFUN(_IO_file_seekoff, (fp, offset, dir, mode), _IO_pos_t result; _IO_off_t delta, new_offset; long count; + /* POSIX.1 8.2.3.7 says that after a call the fflush() the file + offset of the underlying file must be exact. */ + int must_be_exact = (fp->_IO_read_base == fp->_IO_read_end + && fp->_IO_write_base == fp->_IO_write_ptr); if (mode == 0) dir = _IO_seek_cur, offset = 0; /* Don't move any pointers. */ @@ -503,7 +513,8 @@ DEFUN(_IO_file_seekoff, (fp, offset, dir, mode), else { count = _IO_SYSREAD (fp, fp->_IO_buf_base, - fp->_IO_buf_end - fp->_IO_buf_base); + (must_be_exact + ? delta : fp->_IO_buf_end - fp->_IO_buf_base)); if (count < delta) { /* We weren't allowed to read, but try to seek the remainder. */ -- cgit 1.4.1
