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/stdio/fseek.c | 18 +++++++++--------- 1 file changed, 9 insertions(+), 9 deletions(-) (limited to 'newlib/libc/stdio/fseek.c') diff --git a/newlib/libc/stdio/fseek.c b/newlib/libc/stdio/fseek.c index c78d2b26c..099a95892 100644 --- a/newlib/libc/stdio/fseek.c +++ b/newlib/libc/stdio/fseek.c @@ -138,7 +138,7 @@ _DEFUN(_fseek_r, (ptr, fp, offset, whence), CHECK_INIT (ptr, fp); - _flockfile (fp); + _newlib_flockfile_start (fp); /* If we've been doing some writing, and we're in append mode then we don't really know where the filepos is. */ @@ -154,7 +154,7 @@ _DEFUN(_fseek_r, (ptr, fp, offset, whence), if ((seekfn = fp->_seek) == NULL) { ptr->_errno = ESPIPE; /* ??? */ - _funlockfile (fp); + _newlib_flockfile_exit (fp); return EOF; } @@ -179,7 +179,7 @@ _DEFUN(_fseek_r, (ptr, fp, offset, whence), curoff = seekfn (ptr, fp->_cookie, (_fpos_t) 0, SEEK_CUR); if (curoff == -1L) { - _funlockfile (fp); + _newlib_flockfile_exit (fp); return EOF; } } @@ -204,7 +204,7 @@ _DEFUN(_fseek_r, (ptr, fp, offset, whence), default: ptr->_errno = EINVAL; - _funlockfile (fp); + _newlib_flockfile_exit (fp); return (EOF); } @@ -263,7 +263,7 @@ _DEFUN(_fseek_r, (ptr, fp, offset, whence), if ((long)target != target) { ptr->_errno = EOVERFLOW; - _funlockfile (fp); + _newlib_flockfile_exit (fp); return EOF; } @@ -319,7 +319,7 @@ _DEFUN(_fseek_r, (ptr, fp, offset, whence), FREEUB (ptr, fp); fp->_flags &= ~__SEOF; memset (&fp->_mbstate, 0, sizeof (_mbstate_t)); - _funlockfile (fp); + _newlib_flockfile_exit (fp); return 0; } @@ -349,7 +349,7 @@ _DEFUN(_fseek_r, (ptr, fp, offset, whence), fp->_r -= n; } memset (&fp->_mbstate, 0, sizeof (_mbstate_t)); - _funlockfile (fp); + _newlib_flockfile_exit (fp); return 0; /* @@ -361,7 +361,7 @@ dumb: if (_fflush_r (ptr, fp) || seekfn (ptr, fp->_cookie, offset, whence) == POS_ERR) { - _funlockfile (fp); + _newlib_flockfile_exit (fp); return EOF; } /* success: clear EOF indicator and discard ungetc() data */ @@ -379,7 +379,7 @@ dumb: is performed. */ fp->_flags &= ~__SNPT; memset (&fp->_mbstate, 0, sizeof (_mbstate_t)); - _funlockfile (fp); + _newlib_flockfile_end (fp); return 0; } -- cgit v1.2.3
