scandir(3) and alphasort(3) are part of POSIX-2008, so don't require
_NETBSD_SOURCE to use them.

branches: 1.37.2;
Make fdopendir visible according to POSIX.1 spec.

scandir/alphasort take "const struct dirent **" not "const void *" in
modern unix. since we claim to be 'IEEE Std 1003.1-2008', make it so.

rename dd_rewind to dd_internal so that it can be re-used to implement

expose unlocked versions of readdir and telldir.

Fix opendir30 screwup and sort the compat defs for clarity.

compat code reorg

64 bit inode changes

de-__P -- the hack is long since useless. Discussed with christos,
matt, kleink, others. Approved by christos.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22270, verified by myself.

add mutex locking and dirent_r.

Fix things so that _NETBSD_SOURCE correctly exposes the dirfd() and
the insides of struct _dirdesc. Also make the existence of struct
_dirdesc visible to POSIX applications since this is less ugly than
pretending that DIR is a void *.

Add a new feature-test macro, _NETBSD_SOURCE. If this is defined
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.

make scandir(3)'s 3rd argument take a function that takes a *const*
struct dirent *, rather than non-const. this makes scandir(3) the
same as the scandir implementations in libiberty and glibc, and the
select function has no need to modify the dirent.

Move <null.h> to <sys/null.h> for the purpose of avoiding conflicts due to
std C headers including it, and a kernel module written in C++ would benfit
as well.

For the benefit of G++'s null pointer constant implementation, #define NULL
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.

Reorganize name space protection.

oops. Checked in wrong dirent.h version. Add missing getdents prototype
to this one.

Correct comment: getdirentries() -> getdents()

Added missing __seekdir prototype

Changed to unconditionally include <sys/types.h> as required by X/Open XPG4.2.

KERNEL -> _KERNEL

Sync with CSRG.

new RCS ID format.

branches: 1.6.2;
Update to 4.4-Lite version.

Struct dirent definition moved to <sys/dirent.h>.

Expand "u_long" & "u_short" to "unsigned long" and "unsigned short".
Some programs (like NSCA httpd) include <dirent.h> without first including
<sys/types.h> so the u_foo types aren't declared. I don't think POSIX.1
allows us to include <sys/types.h> in <dirent.h> either.

Add RCS identifiers.

Removed bugs and memory leaks from the directory functions.
