so make it marginally less broken so that it works with other compilers
than gcc.
Probably the check can be removed, I doubt anyone will try to use gcc1
anymore.
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.
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.
by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.
This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
!defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.
I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them. In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.
Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.
implementation in not permitting a "name=value" argument.
* Add a conforming __unsetenv13() and do function renaming for
unsetenv(); preserve old symbol with old behavior.
* Make visible setenv() and unsetenv() for 1003.1-2001 feature selection
macros; resolves PR standards/20479.
a user-supplied format string against a fallback format string to ensure
that they will consume arguments of the same type.
libc minor bump for new API entry point.
- MB_LEN_MAX is increased to 32.
- To ensure binary compatibility for old executables
under multibyte locale, versioned setlocale is added.
- __mb_len_cur definision is added in setlocale.c
and enable it in stdlib.h .
It is also important for multibyte locale stuffs,
but I just forgot.
as __null with egcs 1.0 (GCC 2.90) and above. As several headers are affected
by this change, move the definition into a new header file, <null.h>, to ease
maintenance.
issues of the XPG.
* Move setkey() prototype from <unistd.h> to this file. (XPG4)
* Move mkstemp(), mktemp(), ttyslot() and valloc() prototypes from <unistd.h>
to this file. (XPG4.2)
merge (ints -> longs). The only platform on which this might have caused
a problem is the Alpha, and it happens to be safe because the first 6 arguments
are passed in registers on the Alpha (and are thus implicitly promoted to
longs anyhow).
