- add __SAFE flag, to indicate that we want async-signal-safe functionality
only.
- add snprintf_ss, and vsnprintf_ss; these are undocumented on purpose.
From the redhat web page:
http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/gcc/offsetof.html
__offsetof__ (expression)
is equivalent to the parenthesized expression, except that the
expression is considered an integral constant expression even if
it contains certain operators that are not normally permitted in
an integral constant expression. Users should never use __offsetof__
directly; the only valid use of __offsetof__ is to implement the
offsetof macro in <stddef.h>.
g++-3 does not have a built-in offsetof(), but we cannot use the c version,
otherwise we break with -Wold-style-cast.
Inspired by the DF version, but a bit different.
additional argument to read the ttys information from an alternate path
istead of _PATH_TTYS.

Mostly from <apb>.
Bump libc minor.

Discussed with core. I may need to go farther than this but for now
compilations done with gcc -ansi (i.e. firefox) will be okay.
format. Unfortunately this means that all dumps taken from the time of
the 64 bit inode changes (August 16th) will become unreadable with this
commit. To make them readable again, you can back-out this commit temporarily.
Please note, that I am not adding 64 bit inode support to the format on
purpose right now, because supporting 64 bit inodes on-disk will require
additional changes, and it is more appropriate to add such support then.
system-specific values. Submitted by Chris Demetriou in Nov 1995 (!)
in PR kern/1781, modified only slighly by me.
This is enabled on a per-mount basis with the MNT_MAGICLINKS mount
flag. It can be enabled at mountroot() time by building the kernel
with the ROOTFS_MAGICLINKS option.
The following magic strings are supported by the implementation:
@machine value of MACHINE for the system
@machine_arch value of MACHINE_ARCH for the system
@hostname the system host name, as set with sethostname()
@domainname the system domain name, as set with setdomainname()
@kernel_ident the kernel config file name
@osrelease the releaes number of the OS
@ostype the name of the OS (always "NetBSD" for NetBSD)
Example usage:
mkdir /arch/i386/bin
mkdir /arch/sparc/bin
ln -s /arch/@machine_arch/bin /bin
and install ${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-disklabel,
${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-fdisk by "reaching over" to
the sources in ${NETBSDSRCDIR}/sbin/{disklabel fdisk}/.
To avoid clashes with a build-host's header files, especially on
*BSD, the host-tools versions of fdisk and disklabel search for
#includes such as disklabel.h, disklabel_acorn.h, disklabel_gpt.h,
and bootinfo.h in a new #includes namespace, nbinclude/. That is,
they #include <nbinclude/sys/disklabel.h>, <nbinclude/machine/disklabel.h>,
<nbinclude/sparc64/disklabel.h>, instead of <sys/disklabel.h> and
such. I have also updated the system headers to #include from
nbinclude/-space when HAVE_NBTOOL_CONFIG_H is #defined.
have been checked, so that the linker does not warn us. There are valid
uses for mktemp() such as for creating filenames that are going to be
targets of the rename system call. Discussed with lukem.
has also mandated <sys/time.h> to be included, which is now sufficient
for the prototype and all related declarations; thus the local duplicate
of the prototype can be removed. Approved by Christos.
that a strictly conforming C program uses that name itself, so it had to
be removed. Also put the long comment above the #if 0, because it describes
the #if, not the isblank() macro. Added two blank lines to make the grouping
clear. Approved by kleink.
1003.1-2001, and leave the select() prototype in <unistd.h> for
compatibility. To allow for transition, reorganization of this is
deferred until netbsd-3 gets branched.
* Make vfprintf_unlocked() an internal function, c.f. __svfscanf_unlocked().
* Add internal names for arc4random(), endnetpath(), fhstatvfs(),
fstatvfs(), mkstemp(), shquote(), statvfs(), taddr2uaddr(), uaddr2taddr(),
uuid_create_nil(), uuid_is_nil(), and wcwidth().
* Include namespace.h where supposed to.
user visible namespace.
These weren't supported interfaces for a while (it just happened to
work with COMPAT_16 kernels).
There are still internal uses in compat code and as jmp_buf format,
but this is all md code which uses <machine/signal.h>.
with christos' agreement
that the "int maxgroups" and "int *ngroups" parameters are separated into
two separate parameters which makes it possible to call multiple nsswitch
back-ends and have the results correctly merged.
getgrouplist(3) is now implemented using getgroupmembership(3).
Proposed on tech-userlevel on December 1, 2004.
It tells you the major device number for whatever character or block
device you ask it. This is sort of the inverse of devname(3) but not
quite, since it's backed by the kernel (sysctl's kern.drivers
information) and not a database cobbled together from the contents of
the filesystem.
to be transformed into the do-nothing-when-libpthread-isn't-linked libc
stub names. This will permit library code that uses <pthread.h> and pthread
functions "defensively" to not need to link against libpthread and not need
to be patched to the threadlib.h API.
the 1003.1-2001 Thread Safe Functions (TSF) getgrnam_r(3) and getpwnam_r(3).
These are not implemented in sysctl(3) "user.*", since that adds a lot
of complexity in the implementation for no real benefit.
The cast just stops gcc detecting places where the functions are
passed a 'char' variable - and will index off the array for byte values
0x80 to 0xff.
All (I hope) of the places in the netbsd sources where this was a
potential problem have had an (unsigned char) cast applied.
Christos said he'll fix any fallout I've missed.
methods use va_list in a manner that is directly related to the public API.
This makes it much easier to write dynamic nsswitch backends for getpwent(3).
Per my proposal on tech-userlevel.
Implement getpwgid_r() and getpwnam_r() APIs per the POSIX 1003.1, 2004 Ed.
These aren't fully reentrant or threadsafe yet, because the compat stuff
currently uses non-reentrant data sources (getnetgrent(3), getpwent(3)),
and there is probably some locking to be improved in the backends.
This will be fixed in the near future.
We also need to add _SC_GETPW_R_SIZE_MAX to sysconf(3).
Fix the compat `+' prototype override so getpwnam(3) and getpwuid(3) DTRT.
Improve the description of pw_class and pw_gecos.

bitrange for nsdispatch(3) return values.

NS_STATUSMASK before nsdispatch(3) returns it.
