| | | | | | | | Document that getopt_long(3) can and will accept unique abbreviated long option names. This feature has been present since getopt_long(3) was first released in NetBSD 1.5. This is also standard GNU getopt_long(3) behavior. ok millert

* _FD_LOCK/UNLOCK() is libpthread specific and not needed for librthread, sokurt2007-06-051-21/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | isolate its usage to libpthread only and replace with generic non-static mutex support in the one place it is needed: - remove _FD_LOCK/UNLOCK from lseek and ftruncate in libc and make the functions weak so that libpthread can override with its own new versions that do the locking. - remove _thread_fd_lock/unlock() weak functions from libc and adjust libpthread for the change. - add generic _thread_mutex_lock/unlock/destroy() weak functions in libc to support non-static mutexes in libc and add libpthread and librthread implementations for them. libc can utilize non-static mutexes via the new _MUTEX_LOCK/UNLOCK/DESTROY() macros. Actually these new macros can support both static and non-static mutexes but currently only using them for non-static. - make opendir/closedir/readdir/readdir_r/seekdir/telldir() thread-safe for both thread libraries by using a non-static mutex in the struct _dirdesc (typedef DIR), utilizing it in the *dir functions and remove remaining and incorrect _FD_LOCK/UNLOCK() use in libc. - add comments to both thread libraries to indicate libc depends on the current implementation of static mutex initialization. suggested by marc@ - major bump libc and libpthread due to function removal, structure change and weak symbol conversions. okay marc@, tedu@
