CVS Repository/ src/ include/ string.h

The improbable occurred: strlcpy(3) and strlcat(3) are in POSIX-2024.
memmem(3) was also added.  Update #include visibility and manpages
and add restrict qualifiers.

"never thought I'd see this day" millert@

strmode takes a mode_t, not an int; prompted by Collin Funk.
ok kettenis@ deraadt@ tb@

New POSIX xlocale implementation written from scratch.
Complete in the sense that all POSIX *locale(3) and *_l(3) functions
are included, but in OpenBSD, we of course only really care about
LC_CTYPE and we only support ASCII and UTF-8.

With important help from kettenis@, guenther@, and jca@.
Repeated testing in ports bulk builds by naddy@.
Additional testing by jca@, sebastia@, dcoppa@, and others.
OK kettenis@ dcoppa@, and guenther@ on an earlier version.
Riding guenther@'s libc/librthread major bump.

Move the 10 (!) defintions of NULL to their own mini header file and
update the NULL definition for C++11.  OK deraadt@ guenther@ kettenis@

POSIX says that ffs(), strcasecmp(), strncasecmp(), r?index() and
the b* byte functions belong in strings.h, not string.h so break
them out of string.h into a new strings.h.  As long as there is no
POSIX or X/OPEN define in use string.h will pull in strings.h.
OK naddy@ deraadt@

Delete duplicate conditional

diff from frantisek holop (minusf (at) obiit.org)

Add timingsafe_memcmp().

ok deraadt, jmc, tedu

add explicit_bzero to libc. implementation subject to change, but start
the ball rolling. ok deraadt.

Add an implementation of memmem() -- from FreeBSD with some tweaks.
Requires a libc minor bump, committing now so that we have up-to-date
snapshots for the upcoming hackathon.

joint work with millert@
man page bits ok jmc@
input and ok millert@, guenther@, deraadt@

Add 'restrict' per POSIX, per prodding by tedu@.  (Might permit more warnings?)
Tweak standards exposure of memchr (never) and strdup (POSIX-2008)
Remove unnecessary tests of __BSD_VISIBLE

ok millert@

strsignal() was added to POSIX-2008; strerror_r() was in the base
of POSIX-2001, without the XSI qualifier.  Adjust conditionals to match.

ok millert@

Add stpcpy() and stpncpy(), pointless crap that made it into POSIX.
Includes friendly linker warning to wake up those dumb enough to use it.

Committing for kettenis@, who ran away to the hills after writing it

As pointed out by Richard Guenther our definition
of NULL was incorrect for c++ compilers that aren't
gcc (or pretend to be gcc like clang).

ok miod@

Define NULL as a void * instead of a long integer, as required by Single Unix.
Kernel and bootblocks still use the old 0L value until all the NULL abuses
in the code are fixed.

Add timingsafe_bcmp(3) to libc, mention that it's already in the
kernel in kern(9), and remove it from OpenSSH.

ok deraadt@, djm@

add posix_madvise, posix_memalign, strndup, and strnlen.  mostly from
brad and millert, with hints from guenther, jmc, and otto I think.
ok previous.

add memrchr(3)

Adapt things to use __type_t instead of _BSD_TYPE_T_
Add new sys/_types.h header
Include machine/_types.h or sys/_types.h where applicable

First step in include files overhaul.  Use __FOO_VISIBLE (as defined
in sys/cdefs.h) instead of _FOO_SOURCE.  Also fix several namespace
pollution issues, including the byte order defines.  OK deraadt@

strcasestr(3), a case-insensitive version of strstr(3).  already in netbsd
and freebsd, apparently written by torek, the man we never see anymore;
submitted by jcs, but he is not around right now for the libc major crank
so i sneak it in for him

add bounds check for src pointer in bcopy(3) as well as dest pointer,
noticed by millert@

add __bounded__ attributes for userland headers; enabled with -Wbounded
ok deraadt@

backout the __bounded__ attributes for a while; requested by deraadt@

Mark various standard library functions with the __bounded__ attribute.
You must have an up-to-date gcc for this!
deraadt@ ok

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999.  Proofed by myself and Theo.

add prototype for strerror_r

NULL is now 0L so it is the same size as a pointer.
OK mickey@ and discussed with deraadt@

Part one of userland __P removal.  Done with a simple regexp with some minor hand editing to make comments line up correctly.  Another pass is forthcoming that handles the cases that could not be done automatically.

Be thorough about NULL as __null for C++.

Add thread-safety to libc, so that libc_r will build (on i386 at least).
All POSIX libc api now there (to P1003.1c/D10)
  (more md stuff is needed for other libc/arch/*)
  (setlogin is no longer a special syscall)
Add -pthread option to gcc (that makes it use -lc_r and -D_POSIX_THREADS).
Doc some re-entrant routines
Add libc_r to intro(3)
dig() uses some libc srcs and an extra -I was needed there.
Add more md stuff to libc_r.
Update includes for the pthreads api
Update libc_r TODO

protos for strlcat, strlcpy

move proto to unistd.h

Well, as we are heading for a release people are encouraged to rebuild their
entire trees for testing anyway, I might as well do this intrusive touching
of include files now.  Added openBSD tags.
