From 4aa28d8ae279329f2b46c92e05b0bf457f07b9af Mon Sep 17 00:00:00 2001 From: Corinna Vinschen Date: Wed, 30 May 2012 08:58:42 +0000 Subject: * libc/stdio/local.h (_newlib_flockfile_start): New macro to secure stream related critical section against thread cancellation. (_newlib_flockfile_exit): Ditto. (_newlib_sfp_lock_end): Ditto. (_newlib_sfp_lock_start): Ditto for the list of streams. (_newlib_sfp_lock_exit): Ditto. (_newlib_sfp_lock_end): Ditto. Use aforementioned macros in place of _flockfile/_funlockfile and __sfp_lock_acquire/__sfp_lock_release throughout the code. * libc/stdio/fclose.c: Explicitely disable and re-enable thread cancellation. Explain why. * libc/stdio/freopen.c: Ditto. * libc/stdio64/freopen64.c: Ditto. --- newlib/libc/stdio64/fseeko64.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) (limited to 'newlib/libc/stdio64/fseeko64.c') diff --git a/newlib/libc/stdio64/fseeko64.c b/newlib/libc/stdio64/fseeko64.c index 301d6f54f..b323f97d8 100644 --- a/newlib/libc/stdio64/fseeko64.c +++ b/newlib/libc/stdio64/fseeko64.c @@ -126,7 +126,7 @@ _DEFUN (_fseeko64_r, (ptr, fp, offset, whence), CHECK_INIT (ptr, fp); - _flockfile (fp); + _newlib_flockfile_start (fp); curoff = fp->_offset; @@ -144,7 +144,7 @@ _DEFUN (_fseeko64_r, (ptr, fp, offset, whence), if ((seekfn = fp->_seek64) == NULL) { ptr->_errno = ESPIPE; /* ??? */ - _funlockfile(fp); + _newlib_flockfile_exit(fp); return EOF; } @@ -169,7 +169,7 @@ _DEFUN (_fseeko64_r, (ptr, fp, offset, whence), curoff = seekfn (ptr, fp->_cookie, (_fpos64_t) 0, SEEK_CUR); if (curoff == -1L) { - _funlockfile(fp); + _newlib_flockfile_exit(fp); return EOF; } } @@ -194,7 +194,7 @@ _DEFUN (_fseeko64_r, (ptr, fp, offset, whence), default: ptr->_errno = EINVAL; - _funlockfile(fp); + _newlib_flockfile_exit(fp); return (EOF); } @@ -294,7 +294,7 @@ _DEFUN (_fseeko64_r, (ptr, fp, offset, whence), if (HASUB (fp)) FREEUB (ptr, fp); fp->_flags &= ~__SEOF; - _funlockfile(fp); + _newlib_flockfile_exit(fp); return 0; } @@ -323,7 +323,7 @@ _DEFUN (_fseeko64_r, (ptr, fp, offset, whence), fp->_p += n; fp->_r -= n; } - _funlockfile(fp); + _newlib_flockfile_end(fp); return 0; /* -- cgit v1.2.3
