Daniel Eischen 29ac6bd228 libc MT-safety, part 2. ... Add a lock to FILE. flockfile and friends are now implemented (for the most part) in libc. flockfile_debug is implemented in libc_r; I suppose it's about time to kill it but will do it in a future commit. Fix a potential deadlock in _fwalk in a threaded environment. A file flag (__SIGN) was added to stdio.h that, when set, tells _fwalk to ignore it in its walk. This seemed to be needed in refill.c because each file needs to be locked when flushing. Add a stub for pthread_self in libc. This is needed by flockfile which is allowed by POSIX to be recursive. Make fgetpos() error return value (-1) match man page. Remove recursive calls to locked functions (stdio); I think I've got them all, but I may have missed a couple. A few K&R -> ANSI conversions along with removal of a few instances of "register". $Id$ -> $FreeBSD$ in libc/stdio/rget.c Not objected to: -arch, a few months ago		2001-02-11 22:06:43 +00:00
