* lib: Remove ancient SCCS tags.Warner Losh2023-11-271-3/+0
| | | | | | | | Remove ancient SCCS tags from the tree, automated scripting, with two minor fixup to keep things compiling. All the common forms in the tree were removed with a perl script. Sponsored by: Netflix
* libc: Purge unneeded cdefs.hWarner Losh2023-11-011-1/+0
| | | | | | | | | These sys/cdefs.h are not needed. Purge them. They are mostly left-over from the $FreeBSD$ removal. A few in libc are still required for macros that cdefs.h defines. Keep those. Sponsored by: Netflix Differential Revision: https://reviews.freebsd.org/D42385

* libc: drop "All rights reserved" from Foundation copyrightsEd Maste2022-08-041-1/+1
| | | | | | | | | This has already been done for most files that have the Foundation as the only listed copyright holder. Do it now for files that list multiple copyright holders, but have the Foundation copyright in its own section. Sponsored by: The FreeBSD Foundation
* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025
* Renumber copyright clause 4Warner Losh2017-02-281-1/+1
| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

* The problem is: currently our single byte ctype(3) functions are brokenAndrey A. Chernov2007-10-131-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | for wide characters locales in the argument range >= 0x80 - they may return false positives. Example 1: for UTF-8 locale we currently have: iswspace(0xA0)==1 and isspace(0xA0)==1 (because iswspace() and isspace() are the same code) but must have iswspace(0xA0)==1 and isspace(0xA0)==0 (because there is no such character and all others in the range 0x80..0xff for the UTF-8 locale, it keeps ASCII only in the single byte range because our internal wchar_t representation for UTF-8 is UCS-4). Example 2: for all wide character locales isalpha(arg) when arg > 0xFF may return false positives (must be 0). (because iswalpha() and isalpha() are the same code) This change address this issue separating single byte and wide ctype and also fix iswascii() (currently iswascii() is broken for arguments > 0xFF). This change is 100% binary compatible with old binaries. Reviewied by: i18n@ Notes: svn path=/head/; revision=172619

| | | | | | | | | | | | | | | | | | | | as wrappers around the deprecated 4.4BSD rune functions. This paves the way for state-dependent encodings, which the rune API does not support. - Add __emulated_sgetrune() and __emulated_sputrune(), which are implementations of sgetrune() and sputrune() in terms of mbrtowc() and wcrtomb(). - Rename the old rune-wrapper mbrtowc() and wcrtomb() functions to __emulated_mbrtowc() and __emulated_wcrtomb(). - Add __mbrtowc and __wcrtomb function pointers, which point to the current locale's conversion functions, or the __emulated versions. - Implement mbrtowc() and wcrtomb() as calls to these function pointers. - Make the "NONE" encoding implement mbrtowc() and wcrtomb() directly. All of this emulation mess will be removed, together with rune support, in FreeBSD 6. Notes: svn path=/head/; revision=121845

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
