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/ftello64.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'newlib/libc/stdio64/ftello64.c') diff --git a/newlib/libc/stdio64/ftello64.c b/newlib/libc/stdio64/ftello64.c index 51dcd2796..c4d6da24b 100644 --- a/newlib/libc/stdio64/ftello64.c +++ b/newlib/libc/stdio64/ftello64.c @@ -99,12 +99,12 @@ _DEFUN (_ftello64_r, (ptr, fp), CHECK_INIT (ptr, fp); - _flockfile(fp); + _newlib_flockfile_start(fp); if (fp->_seek64 == NULL) { ptr->_errno = ESPIPE; - _funlockfile(fp); + _newlib_flockfile_exit(fp); return -1L; } @@ -121,7 +121,7 @@ _DEFUN (_ftello64_r, (ptr, fp), pos = fp->_seek64 (ptr, fp->_cookie, (_fpos64_t) 0, SEEK_CUR); if (pos == -1L) { - _funlockfile(fp); + _newlib_flockfile_exit(fp); return pos; } } @@ -146,7 +146,7 @@ _DEFUN (_ftello64_r, (ptr, fp), pos += fp->_p - fp->_bf._base; } - _funlockfile(fp); + _newlib_flockfile_end(fp); return pos; } -- cgit v1.2.3
