* The ORIENTLOCK macro is no longer needed since all functions useTim J. Robbins2002-10-251-7/+0
| | | | | | | FLOCKFILE/FUNLOCKFILE explicitly. Notes: svn path=/head/; revision=105909
* Use a weak reference instead of a macro to make vfscanf an aliasTim J. Robbins2002-10-141-0/+2
| | | | | | | for __vfscanf. Notes: svn path=/head/; revision=105098
* Add implementations of wscanf() and related functions: fwscanf(), swscanf(),Tim J. Robbins2002-09-231-0/+2
| | | | | | | | vfwscanf(), vswscanf(), vwscanf(). As the name suggests, these are wide- character versions of the scanf() family of functions. Notes: svn path=/head/; revision=103856
* The character argument for __ungetwc() should be wint_t instead of wchar_t.Tim J. Robbins2002-09-231-1/+1

* Add an unlocked version of ungetwc(), __ungetwc(), that __vfwscanf()Tim J. Robbins2002-09-221-0/+1

| | | | | | | formatted wide-character output. Notes: svn path=/head/; revision=103739
* Introduce unlocked versions of fputwc() and fgetwc() called __fputwc()Tim J. Robbins2002-09-201-0/+2
| | | | | | | and __fgetwc() which can be used when we know the file is locked. Notes: svn path=/head/; revision=103676
* o Merge <machine/ansi.h> and <machine/types.h> into a new headerMike Barcroft2002-08-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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 Concept by: bde Reviewed by: jake, obrien Notes: svn path=/head/; revision=102227
* Basic support for wide character I/O: getwc(), fgetwc(), getwchar(),Tim J. Robbins2002-08-131-0/+31

* Fix the style of the SCM ID's.David E. O'Brien2002-03-221-1/+0
| | | | | | | I believe have made all of libc .h's as consistent as possible. Notes: svn path=/head/; revision=92991
* Remove __P() usage.David E. O'Brien2002-03-211-23/+23

* Re-arrange my funopen(3) fix to minimize differences with original stdio code,Andrey A. Chernov2001-09-031-0/+2
| | | | | | | | | no functional changes. Add fp->_offset optimization in _SAPP+_SOPT case Notes: svn path=/head/; revision=82838
* Move all stdio internal flags processing and setting out of __sread(),Andrey A. Chernov2001-09-021-0/+1
| | | | | | | | | | | | | __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. Notes: svn path=/head/; revision=82807
* Back out disabling ungetc() at 0, use different solution:Andrey A. Chernov2001-09-011-2/+2
| | | | | | | | keep negative offset internally, but return 0 externally in ftell*() I.e. use 0 now as 'unspecified value' per POSIX ungetc() description. Notes: svn path=/head/; revision=82709
* The same big piece of ftell code repeated in 3 places. Simplify things movingAndrey A. Chernov2001-08-311-0/+1
| | | | | | | | it into one subfunction instead. Try to use real offset in strange cases. Notes: svn path=/head/; revision=82668
* fseek.c:Andrey A. Chernov2001-08-171-1/+1
| | | | | | | | | | | | | | | 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() Notes: svn path=/head/; revision=81817

* Properly initialize a temporary FILE that is allocated off the stack.Daniel Eischen2001-06-041-0/+7
| | | | | | | | | | The change to reuse _up from FILE (to allow FILE to grow without changing size) overlooked FILE being allocated off the stack. Approved by: sobomax Notes: svn path=/head/; revision=77686
* Hide the definition of struct __sFILEX and add the neededDaniel Eischen2001-03-011-0/+10
| | | | | | | | | | 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. Notes: svn path=/head/; revision=73254
* Remove _THREAD_SAFE and make libc thread-safe by default byDaniel Eischen2001-01-241-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Approved by: -arch Notes: svn path=/head/; revision=71579
