79db40061f The ORIENTLOCK macro is no longer needed since all functions use
FLOCKFILE/FUNLOCKFILE explicitly.

af1c9c0e4d Use a weak reference instead of a macro to make vfscanf an alias
for __vfscanf.

1f4ff8506a Add implementations of wscanf() and related functions: fwscanf(), swscanf(),
vfwscanf(), vswscanf(), vwscanf(). As the name suggests, these are wide-
character versions of the scanf() family of functions.

adc106840c The character argument for __ungetwc() should be wint_t instead of wchar_t. 2002-09-23 11:31:18 +00:00

5f147b57ac Add an unlocked version of ungetwc(), __ungetwc(), that __vfwscanf()
will need to use.

8f030a44b8 Introduce unlocked versions of fputwc() and fgetwc() called __fputwc()
and __fgetwc() which can be used when we know the file is locked.

abbd890233 o Merge <machine/ansi.h> and <machine/types.h> into a new header
called <machine/_types.h>.
o <machine/ansi.h> will continue to live so it can define MD clock
  macros, which are only MD because of gratuitous differences between
  architectures.
o Change all headers to make use of this.  This mainly involves
  changing:
    #ifdef _BSD_FOO_T_
    typedef	_BSD_FOO_T_	foo_t;
    #undef _BSD_FOO_T_
    #endif
  to:
    #ifndef _FOO_T_DECLARED
    typedef	__foo_t	foo_t;
    #define	_FOO_T_DECLARED
    #endif

e74101e4ef Basic support for wide character I/O: getwc(), fgetwc(), getwchar(),
putwc(), fputwc(), putwchar(), ungetwc(), fwide().

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

5e00917d95 Re-arrange my funopen(3) fix to minimize differences with original stdio code,
no functional changes.

Add fp->_offset optimization in _SAPP+_SOPT case

924888f977 Move all stdio internal flags processing and setting out of __sread(),
__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.

65efd81290 Back out disabling ungetc() at 0, use different solution:
keep negative offset internally, but return 0 externally in ftell*()
I.e. use 0 now as 'unspecified value' per POSIX ungetc() description.

2ff678f5bb The same big piece of ftell code repeated in 3 places. Simplify things moving
it into one subfunction instead.
Try to use real offset in strange cases.

71b5a4326d fseek.c:
Resulting fseek() offset must fit in long, required by POSIX (pointed by bde),
so add LONG_MAX and final tests for it.

rewind.c:
1) add missing __sinit() as in fseek() it pretends to be.
2) use clearerr_unlocked() since we already lock stream before _fseeko()
3) don't zero errno at the end, it explicitely required by POSIX as the
only one method to test rewind() error condition.
4) don't clearerr() if error happens in _fseeko()

fcd70a7565 Properly initialize a temporary FILE that is allocated off the stack.
The change to reuse _up from FILE (to allow FILE to grow without changing
size) overlooked FILE being allocated off the stack.

45d8008748 Hide the definition of struct __sFILEX and add the needed
lock definitions to it.  flockfile state is now allocated
along with the rest of FILE.  This eliminates the need for a
separate allocation of flockfile state as well as eliminating
the mutex/lock used to serialize its allocation.

d201fe46e3 Remove _THREAD_SAFE and make libc thread-safe by default by
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.  <db.h> 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 <errno.h> from a few files.

Add $FreeBSD$ to a few files in order to pass commitprep.
