From 11eb4dfd2d42417327fc205c649ea32ee623cf92 Mon Sep 17 00:00:00 2001 From: rpj Date: Fri, 18 Aug 2000 08:02:29 +0000 Subject: 2000-08-18 Ross Johnson * Several: Fix typos from scripted edit session yesterday. * nonportable.c (pthread_mutexattr_setforcecs_np): Moved this function from mutex.c. (pthread_getw32threadhandle_np): New function to return the win32 thread handle that the POSIX thread is using. * mutex.c (pthread_mutexattr_setforcecs_np): Moved to new file "nonportable.c". * pthread.h (PTW32_BUILD): Only redefine __except and catch compiler keywords if we aren't building the library (ie. PTW32_BUILD is not defined) - this is safer than defining and then undefining if not building the library. * implement.h: Remove __except and catch undefines. * Makefile (CFLAGS): Define PTW32_BUILD. * GNUmakefile (CFLAGS): Define PTW32_BUILD. * All appropriate: Change Pthread_exception* to ptw32_exception* to be consistent with internal identifier naming. * private.c (ptw32_throw): New function to provide a generic exception throw for all internal exceptions and EH schemes. (ptw32_threadStart): pthread_exit() value is now returned via the thread structure exitStatus element. * exit.c (pthread_exit): pthread_exit() value is now returned via the thread structure exitStatus element. * cancel.c (ptw32_cancel_self): Now uses ptw32_throw. (pthread_setcancelstate): Ditto. (pthread_setcanceltype): Ditto. (pthread_testcancel): Ditto. (pthread_cancel): Ditto. * misc.c (CancelableWait): Ditto. * exit.c (pthread_exit): Ditto. * All applicable: Change PTW32_ prefix to PTW32_ prefix to remove leading underscores from private library identifiers. --- ANNOUNCE | 32 ++++++++++++++++++-------------- 1 file changed, 18 insertions(+), 14 deletions(-) (limited to 'ANNOUNCE') diff --git a/ANNOUNCE b/ANNOUNCE index a7e61c3..9607dd4 100644 --- a/ANNOUNCE +++ b/ANNOUNCE @@ -26,19 +26,14 @@ Change Summary (since the last snapshot) (See the ChangeLog file for details.)
