* Make _fwalk and _cleanup completely internal to libcguenther2016-05-231-4/+2
| | | | ok deraadt@
* Use a Thread Information Block in both single and multi-threaded programs.guenther2016-05-071-3/+12
| | | | | | | | | | | | | | | | | This stores errno, the cancelation flags, and related bits for each thread and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable! Make libpthread dlopen'able by moving the cancelation wrappers into libc and doing locking and fork/errno handling via callbacks that libpthread registers when it first initializes. 'errno' *must* be declared via <errno.h> now! Clean up libpthread's symbol exports like libc. On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec. Testing by various, particularly sthen@ and patrick@ ok kettenis@

* Add fwprintf, swprintf, vfwprintf, vswprintf, vwprintf, and wprintf to libc.stsp2011-04-241-1/+2
| | | | | | Based on our vfprintf etc. implementations. Wide character parts based on NetBSD but with lots of macros expanded. Minor bump for libc. ok kettenis espie
* Fix the handle locking in stdio to use flockfile/funlockfilekurt2009-11-091-1/+6
| | | | | | | | | | | | | internally when and where required. Macros in <stdio.h> are updated to automatically call the underlying functions when the process is threaded to obtain the necessary locking. A private mutex is added to protect __sglue, the internal list of FILE handles, and another to protect the one-time initialization. Some routines in libc that use getc() change to use getc_unlocked() as they're either protected by their own lock or aren't thread-safe routines anyway. committing on behalf of and okay guenther@ now that we have install media space available.

* Change internals of FILE: reuse the unget buffer field to access anespie2005-04-301-5/+7
| | | | | | | | | | | | | | | | extended attribute data structure (pimpl idiom). Idea taken from citrus. Much discussion with deraadt@, otto@, millert@... This is the least disruptive way to extend FILE, since its size can't really change without this being a flag day. So the size doesn't change. Actual additions to the structure will come in separate steps, since this change is nasty enough on its own. Tests by otto@ and others, careful reading of code by otto@ and millert@. This is definitely a major bump, and has been checked to not impact a full ports build.
