Don't override it -# in your configure.ac. -# -# This macro checks for Python and tries to get the include path to -# 'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LDFLAGS) -# output variables. It also exports $(PYTHON_EXTRA_LIBS) and -# $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code. -# -# You can search for some particular version of Python by passing a -# parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please -# note that you *have* to pass also an operator along with the version to -# match, and pay special attention to the single quotes surrounding the -# version number. Don't use "PYTHON_VERSION" for this: that environment -# variable is declared as precious and thus reserved for the end-user. -# -# This macro should work for all versions of Python >= 2.1.0. As an end -# user, you can disable the check for the python version by setting the -# PYTHON_NOVERSIONCHECK environment variable to something else than the -# empty string. -# -# If you need to use this macro for an older Python version, please -# contact the authors. We're always open for feedback. -# -# LICENSE -# -# Copyright (c) 2009 Sebastian Huber <sebastian-huber@web.de> -# Copyright (c) 2009 Alan W.

If found, -# then SWIG is AC_SUBST'd; if not found, then $SWIG is empty.

It -# should have the format: N[.N[.N]] (N is a number between 0 and 999. Only -# the first N is mandatory.) If the version argument is given (e.g. -# 1.3.17), AX_PKG_SWIG checks that the swig package is this version number -# or higher. -# -# As usual, action-if-found is executed if SWIG is found, otherwise -# action-if-not-found is executed. -# -# In configure.in, use as: -# -# AX_PKG_SWIG(1.3.17, [], [ AC_MSG_ERROR([SWIG is required to build..]) ]) -# AX_SWIG_ENABLE_CXX -# AX_SWIG_MULTI_MODULE_SUPPORT -# AX_SWIG_PYTHON -# -# LICENSE -# -# Copyright (c) 2008 Sebastian Huber <sebastian-huber@web.de> -# Copyright (c) 2008 Alan W.

A secondary benefit of using ldns is speed, because ldns is written -in C, and although it is not optimized for performance, it should be a lot -faster than Perl. - -The first main tool to use ldns is Drill, from which part of the library was -derived. From version 1.0.0 on, drill is included in the ldns release -and will not be distributed separately anymore. The library also includes some -other examples and tools to show how it can be used. These can be found in the -examples/ directory in the tarball. - -ldns depends on OpenSSL for it's cryptographic functions. -Feature list - - - Transparent IPv4 and IPv6 support (overridable if necessary), - - TSIG support, - - DNSSEC support; signing and verification, - - small size, - - online documentation as well as manual pages. - -If you want to send us patches please use the code from git. - -\section using_ldns Using ldns - -Almost all interaction between an application and ldns goes through the ldns -data structures (\ref ldns_rr, \ref ldns_pkt, etc.). These are input or -output to the functions of ldns. For example, \ref ldns_zone_new_frm_fp -reads a zone from a \c FILE pointer, and returns an \ref ldns_zone -structure. - - -Let's use Drill as an example. Drill is a tool much like dig, whose most -basic function is to send 1 query to a nameserver and print the response. - -To be able to do this, drill uses the resolver module of ldns, which acts as -a stub resolver. The resolver module uses the net module to actually send -the query that drill requested. It then uses the wire2host module to -translate the response and place it in ldns' internal structures. These are -passed back to drill, which then uses the host2str module to print the -response in presentation format. - -\section gettingstarted Getting Started - -See the \ref design page for a very high level description of the design -choices made for ldns. - -For an overview of the functions and types ldns provides, you can check out -the \ref ldns ldns header file descriptions. - -If you want to see some libdns action, you can read our tutorials: - - \ref tutorial1_mx - - \ref tutorial2_zone - - \ref tutorial3_signzone - -Or you can just use the menu above to browse through the API docs. - -<div style="visibility:hidden;"> -\image html LogoInGradientBar2-y100.png -</div> -*/ - -/** - * \file ldns.h - * - * Including this file will include all ldns files, and define some lookup tables. - */ - -#ifndef LDNS_DNS_H -#define LDNS_DNS_H - -#include <stdio.h> -#include <stdlib.h> - -#include <ldns/util.h> -#include <ldns/buffer.h> -#include <ldns/common.h> -#include <ldns/dane.h> -#include <ldns/dname.h> -#include <ldns/dnssec.h> -#include <ldns/dnssec_verify.h> -#include <ldns/dnssec_sign.h> -#include <ldns/duration.h> -#include <ldns/error.h> -#include <ldns/higher.h> -#include <ldns/host2str.h> -#include <ldns/host2wire.h> -#include <ldns/net.h> -#include <ldns/packet.h> -#include <ldns/rdata.h> -#include <ldns/resolver.h> -#include <ldns/rr.h> -#include <ldns/str2host.h> -#include <ldns/tsig.h> -#include <ldns/update.h> -#include <ldns/wire2host.h> -#include <ldns/rr_functions.h> -#include <ldns/keys.h> -#include <ldns/parse.h> -#include <ldns/zone.h> -#include <ldns/dnssec_zone.h> -#include <ldns/radix.h> -#include <ldns/rbtree.h> -#include <ldns/sha1.h> -#include <ldns/sha2.h> - -#ifdef __cplusplus -extern "C" { -#endif - -#define LDNS_IP4ADDRLEN (32/8) -#define LDNS_IP6ADDRLEN (128/8) -#define LDNS_PORT 53 -#define LDNS_ROOT_LABEL_STR "." -#define LDNS_DEFAULT_TTL 3600 - -/* lookup tables for standard DNS stuff */ - -/** Taken from RFC 2538, section 2.1. */ -extern ldns_lookup_table ldns_certificate_types[]; -/** Taken from RFC 2535, section 7. */ -extern ldns_lookup_table ldns_algorithms[]; -/** Taken from RFC 2538. */ -extern ldns_lookup_table ldns_cert_algorithms[]; -/** rr types */ -extern ldns_lookup_table ldns_rr_classes[]; -/** Response codes */ -extern ldns_lookup_table ldns_rcodes[]; -/** Operation codes */ -extern ldns_lookup_table ldns_opcodes[]; -/** EDNS flags */ -extern ldns_lookup_table ldns_edns_flags[]; - -#ifdef __cplusplus -} -#endif - -#endif /* LDNS_DNS_H */ diff --git a/ldns/ldns/net.h.in b/ldns/ldns/net.h.in deleted file mode 100644 index 2591258..0000000 --- a/ldns/ldns/net.h.in +++ /dev/null @@ -1,254 +0,0 @@ -/* - * net.h - * - * DNS Resolver definitions - * - * a Net::DNS like library for C - * - * (c) NLnet Labs, 2005-2006 - * - * See the file LICENSE for the license - */ - -#ifndef LDNS_NET_H -#define LDNS_NET_H - -#include <ldns/ldns.h> -@include_sys_socket_h@ - -#ifdef __cplusplus -extern "C" { -#endif - -#define LDNS_DEFAULT_TIMEOUT_SEC 5 -#define LDNS_DEFAULT_TIMEOUT_USEC 0 - -/** - * \file - * - * Contains functions to send and receive packets over a network. - */ - -/** - * Sends a buffer to an ip using udp and return the respons as a ldns_pkt - * \param[in] qbin the ldns_buffer to be send - * \param[in] to the ip addr to send to - * \param[in] tolen length of the ip addr - * \param[in] timeout the timeout value for the network - * \param[out] answersize size of the packet - * \param[out] result packet with the answer - * \return status - */ -ldns_status ldns_udp_send(uint8_t **result, ldns_buffer *qbin, const struct sockaddr_storage *to, socklen_t tolen, struct timeval timeout, size_t *answersize); - -/** - * Send an udp query and don't wait for an answer but return - * the socket - * \param[in] qbin the ldns_buffer to be send - * \param[in] to the ip addr to send to - * \param[in] tolen length of the ip addr - * \param[in] timeout *unused*, was the timeout value for the network - * \return the socket used or -1 on failure - */ -int ldns_udp_bgsend2(ldns_buffer *qbin, const struct sockaddr_storage *to, socklen_t tolen, struct timeval timeout); - -/** - * Send an udp query and don't wait for an answer but return - * the socket - * This function has the flaw that it returns 0 on failure, but 0 could be a - * valid socket.
