christos 663f790f35 remove redundant declarations. 2000-12-20 20:51:08 +00:00
itojun babc498cc8 implement EDNS0 support, as EDNS0 support will be made mandatory for
IPv6 transport-ready resolvers/DNS servers.  need careful configuration
when enable it. (default config is not affected).
see manpage for details.

XXX visible symbol __res_opt() is added, however, it is not supposed to be
called from outside, libc minor is not bumped.

itohy 7daefc5a5a Passing "char" values to ctype(3) functions is problematic.
If an argument of a ctype function is outside "unsigned char"
and if it is not EOF, the behavior is undefined.

The isascii(3) is the sole exception of above and it was used to
be used to check a value was valid for other ctype functions in
ancient systems.  On modern systems, the ctype functions take
all values of "unsigned char", and this check is obsolete and
even wrong for non-ASCII systems.  However, we leave the isascii()
untouched for now, so as not to change the current behavior.

itojun c3f3ab4c5c sync with BIND 4.9.7. correct boundary checking broken by delint mistake
(auto increment evaluation order).  costmetic changes.

mycroft 605490369c Delint.
Remove trailing ; from uses of __weak_alias().  The macro inserts this if
needed.

lukem d896261208 back out the #ifdef _DIAGNOSTIC argument checks; too many people complained.
_DIAGASSERT() is still retained.
1999-09-20 04:38:56 +00:00
lukem b48252f365 * use _DIAGASSERT() to check pointer arguments against NULL and file
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
  and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.

the first two items result in the addition of code similar to the
following in various functions:

		_DIAGASSERT(path != NULL)
	#ifdef _DIAGNOSTIC
		if (path == NULL) {
			errno = EFAULT;
			return (-1);
		}
	#endif

kleink 0b11c41974 Since these files are shared with parts of the BIND-4 userland (outside libc),
do the internal symbol renaming dance only if inside the libc build environment.

jtc 43fa6fe319 If port provides __weak_alias(), provide an Standard C and POSIX pure
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore.  The library will use those
names internally.  Weak aliases are used to provide the original names
to the API.

This is only the first part of this change.  It is most of the functions
which are implemented in C for all NetBSD ports.  Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.
