include <sys/param.h> (to operate in legacy mode) or if it wishes to operate
in the POSIX world use <limits.h>

of the functions prototyped here exist in libc, making it useless.

not be in scope, so hardcode as 256. Other options have more downside.
|

This hides the unavoidably cruddy sys/param.h namespace in some programs.
Little impact, because many programs are cruddy and still get it via
other includes.

instead, #define to __builtin_alloca. if that doesn't work, you're hosed.

rewrite the function to be simpler as well. the compiler can unroll the
loop for us if necessary.

to returning strong random by default, source from arc4random(3).
Parameters to the seeding functions are ignored, and the subsystems remain
in strong random mode. If you wish the standardized deterministic mode,
call srand_deterministic(), srandom_determistic(), srand48_deterministic(),
seed48_deterministic() or lcong48_deterministic() instead.
The re-entrant functions rand_r(), erand48(), nrand48(), jrand48() are
unaffected by this change and remain in deterministic mode (for now).
Verified as a good roadmap forward by auditing 8800 pieces of software.
Roughly 60 pieces of software will need adaptation to request the
deterministic mode.
Violates POSIX and C89, which violate best practice in this century.

version with zero args, so it should only be visible if __BSD_VISIBLE
(and not also for __XPG_VISIBLE). Contrawise, readlink() has been
part of base POSIX since 1995, so move to proper #if area for that.
Move crypt_checkpass() to the pure-BSD section of the file.

when creating them: mkostemp(), mkostemps(), the 'e' mode letter for
fopen(), freopen(), fdopen(), and popen(). The close-on-exec flag will
be cleared by the action created by posix_spawn_file_actions_adddup2().
Also, add support for the C11 'x' mode letter for fopen() and freopen(),
setting O_EXCL when possibly creating files.
Note: this requires kernel support for pipe2() and dup3()!

* you can #include <sys/endian.h> instead of <machine/endian.h>,
and ditto <endian.h> (fixes code that pulls in <sys/endian.h> first)
* those will always export the symbols that POSIX specified for
<endian.h>, including the new {be,le}{16,32,64}toh() set. c.f.
http://austingroupbugs.net/view.php?id=162
if __BSD_VISIBLE then you also get the symbols that our <machine/endian.h>
currently exports (ntohs, NTOHS, dlg's bemtoh*, etc)
* when doing POSIX compiles (not __BSD_VISIBLE), then <netinet/in.h> and
<arpa/inet.h> will *stop* exporting the extra symbols like BYTE_ORDER
and betoh*

buffersize is enforced strictly, this supplies sufficient entropy
payload to act as seed material. Discourage general use of this
API, but lock down this function name as the go-to for userland
PRNG seeding. Improve documentation.

I accepted that he's right (again) to seperate this out from heavy
sysctl API and this will simply a variety of things. Functionname
is not used by anyone in the ports tree, so we guess we can use it.
Shocking that no application has a function called this.

It's not a standard interface, so it doesn't belong in libc.
I hate duplicating the code in client programs, so do beck@, kettenis@,
schwarze@, millert@, miod@... and they agree with libutil.

This is a getaddrinfo() flag that is defined thusly in RFC 3493:
If the AI_ADDRCONFIG flag is specified, IPv4 addresses shall be
returned only if an IPv4 address is configured on the local system,
and IPv6 addresses shall be returned only if an IPv6 address is
configured on the local system. The loopback address is not
considered for this case as valid as a configured address.
For example, when using the DNS, a query for AAAA records should
occur only if the node has at least one IPv6 address configured
(other than IPv6 loopback) and a query for A records should occur
only if the node has at least one IPv4 address configured (other
than the IPv4 loopback).
The flag is set by default when hints is NULL.
