src/lib/libc/stdio/refill.c, branch release/5.2.1

Basic support for wide character I/O: getwc(), fgetwc(), getwchar(),

2002-08-13T09:30:41Z

putwc(), fputwc(), putwchar(), ungetwc(), fwide().

Fix the style of the SCM ID's.

I believe have made all of libc .c's as consistent as possible.

Remove __P() usage.

2002-03-21T22:49:10Z

Re-arrange my funopen(3) fix to minimize differences with original stdio code,

2001-09-03T02:24:37Z

no functional changes. Add fp->_offset optimization in _SAPP+_SOPT case

Fix bug in off_t overflow checking: if fp->_offset overflows, just remove

2001-09-02T19:52:09Z

__SOFF flag (i.e. we don't have offset) instead of returning EOVERFLOW. It allows again continious reading from non-stop stream.

Move all stdio internal flags processing and setting out of __sread(),

2001-09-02T19:10:10Z

__swrite() and __sseek() to higher level. According to funopen(3) they all are just wrappers to something like standard read(2), write(2) and lseek(2), i.e. must not touch stdio internals because they are replaceable with any other functions knows nothing about stdio internals. See example of funopen(3) usage in sendmail sources f.e. NOTE: this is original stdio bug, not result of my range checkin added.

Fix style breakage.

Fix the current libc breakage in current:

2001-02-16T06:11:22Z

o Back out the __std* stuff. Can't figure out how to do this right now, so we'll save it for late. o use _up as a pointer for extra fields that we need to access. o back out the libc major version bump. Submitted by: green reviewed by: peter, imp, green, obrien (to varying degrees). We'll fix the "how do we stop encoding sizeof(FILE) in binaries" part later.

libc MT-safety, part 2.

2001-02-11T22:06:43Z

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

Remove _THREAD_SAFE and make libc thread-safe by default by

2001-01-24T13:01:12Z

adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in. Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo. Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible. Remove uneeded includes of from a few files. Add $FreeBSD$ to a few files in order to pass commitprep. Approved by: -arch
