Nmap is also a registered trademark of the Nmap Project. * 7 * This program is free software; you may redistribute and/or modify it * 8 * under the terms of the GNU General Public License as published by the * 9 * Free Software Foundation; Version 2 ("GPL"), BUT ONLY WITH ALL OF THE * 10 * CLARIFICATIONS AND EXCEPTIONS DESCRIBED HEREIN. This guarantees your * 11 * right to use, modify, and redistribute this software under certain * 12 * conditions. If you wish to embed Nmap technology into proprietary * 13 * software, we sell alternative licenses (contact sales@nmap.com). * 14 * Dozens of software vendors already license Nmap technology such as * 15 * host discovery, port scanning, OS detection, version detection, and * 16 * the Nmap Scripting Engine. * 17 * * 18 * Note that the GPL places important restrictions on "derivative works", * 19 * yet it does not provide a detailed definition of that term. To avoid * 20 * misunderstandings, we interpret that term as broadly as copyright law * 21 * allows. For example, we consider an application to constitute a * 22 * derivative work for the purpose of this license if it does any of the * 23 * following with any software or content covered by this license * 24 * ("Covered Software"): * 25 * * 26 * o Integrates source code from Covered Software. * 27 * * 28 * o Reads or includes copyrighted data files, such as Nmap's nmap-os-db * 29 * or nmap-service-probes. * 30 * * 31 * o Is designed specifically to execute Covered Software and parse the * 32 * results (as opposed to typical shell or execution-menu apps, which will * 33 * execute anything you tell them to). * 34 * * 35 * o Includes Covered Software in a proprietary executable installer. The * 36 * installers produced by InstallShield are an example of this. Including * 37 * Nmap with other software in compressed or archival form does not * 38 * trigger this provision, provided appropriate open source decompression * 39 * or de-archiving software is widely available for no charge. For the * 40 * purposes of this license, an installer is considered to include Covered * 41 * Software even if it actually retrieves a copy of Covered Software from * 42 * another source during runtime (such as by downloading it from the * 43 * Internet). * 44 * * 45 * o Links (statically or dynamically) to a library which does any of the * 46 * above. * 47 * * 48 * o Executes a helper program, module, or script to do any of the above. * 49 * * 50 * This list is not exclusive, but is meant to clarify our interpretation * 51 * of derived works with some common examples. Other people may interpret * 52 * the plain GPL differently, so we consider this a special exception to * 53 * the GPL that we apply to Covered Software. Works which meet any of * 54 * these conditions must conform to all of the terms of this license, * 55 * particularly including the GPL Section 3 requirements of providing * 56 * source code and allowing free redistribution of the work as a whole. * 57 * * 58 * As another special exception to the GPL terms, the Nmap Project grants * 59 * permission to link the code of this program with any version of the * 60 * OpenSSL library which is distributed under a license identical to that * 61 * listed in the included docs/licenses/OpenSSL.txt file, and distribute * 62 * linked combinations including the two. * 63 * * 64 * The Nmap Project has permission to redistribute Npcap, a packet * 65 * capturing driver and library for the Microsoft Windows platform. * 66 * Npcap is a separate work with it's own license rather than this Nmap * 67 * license. Since the Npcap license does not permit redistribution * 68 * without special permission, our Nmap Windows binary packages which * 69 * contain Npcap may not be redistributed without special permission. * 70 * * 71 * Any redistribution of Covered Software, including any derived works, * 72 * must obey and carry forward all of the terms of this license, including * 73 * obeying all GPL rules and restrictions. For example, source code of * 74 * the whole work must be provided and free redistribution must be * 75 * allowed. All GPL references to "this License", are to be treated as * 76 * including the terms and conditions of this license text as well. * 77 * * 78 * Because this license imposes special exceptions to the GPL, Covered * 79 * Work may not be combined (even as part of a larger work) with plain GPL * 80 * software. The terms, conditions, and exceptions of this license must * 81 * be included as well. This license is incompatible with some other open * 82 * source licenses as well. In some cases we can relicense portions of * 83 * Nmap or grant special permissions to use it in other open source * 84 * software. Please contact fyodor@nmap.org with any such requests. * 85 * Similarly, we don't incorporate incompatible open source software into * 86 * Covered Software without special permission from the copyright holders. * 87 * * 88 * If you have any questions about the licensing restrictions on using * 89 * Nmap in other works, we are happy to help. As mentioned above, we also * 90 * offer an alternative license to integrate Nmap into proprietary * 91 * applications and appliances. These contracts have been sold to dozens * 92 * of software vendors, and generally include a perpetual license as well * 93 * as providing support and updates. They also fund the continued * 94 * development of Nmap. Please email sales@nmap.com for further * 95 * information. * 96 * * 97 * If you have received a written license agreement or contract for * 98 * Covered Software stating terms other than these, you may choose to use * 99 * and redistribute Covered Software under those terms instead of these. * 100 * * 101 * Source is provided to this software because we believe users have a * 102 * right to know exactly what a program is going to do before they run it. * 103 * This also allows you to audit the software for security holes. * 104 * * 105 * Source code also allows you to port Nmap to new platforms, fix bugs, * 106 * and add new features. You are highly encouraged to send your changes * 107 * to the dev@nmap.org mailing list for possible incorporation into the * 108 * main distribution. By sending these changes to Fyodor or one of the * 109 * Insecure.Org development mailing lists, or checking them into the Nmap * 110 * source code repository, it is understood (unless you specify * 111 * otherwise) that you are offering the Nmap Project the unlimited, * 112 * non-exclusive right to reuse, modify, and relicense the code. Nmap * 113 * will always be available Open Source, but this is important because * 114 * the inability to relicense code has caused devastating problems for * 115 * other Free Software projects (such as KDE and NASM). We also * 116 * occasionally relicense the code to third parties as discussed above. * 117 * If you wish to specify special license conditions of your * 118 * contributions, just say so when you send them. * 119 * * 120 * This program is distributed in the hope that it will be useful, but * 121 * WITHOUT ANY WARRANTY; without even the implied warranty of * 122 * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the Nmap * 123 * license file for more details (it's in a COPYING file included with * 124 * Nmap, and also available from https://svn.nmap.org/nmap/COPYING) * 125 * * 126 ***************************************************************************/ 127 128 /* $Id: xml.h 15135 2009-08-19 21:05:21Z david $ */ 129 130 #ifndef _XML_H 131 #define _XML_H 132 133 #include <stdarg.h> 134 135 int xml_write_raw(const char *fmt, ...) __attribute__ ((format (printf, 1, 2))); 136 int xml_write_escaped(const char *fmt, ...) __attribute__ ((format (printf, 1, 2))); 137 int xml_write_escaped_v(const char *fmt, va_list va) __attribute__ ((format (printf, 1, 0))); 138 139 int xml_start_document(const char *rootnode); 140 141 int xml_start_comment(); 142 int xml_end_comment(); 143 144 int xml_open_pi(const char *name); 145 int xml_close_pi(); 146 147 int xml_open_start_tag(const char *name, const bool write = true); 148 int xml_close_start_tag(const bool write = true); 149 int xml_close_empty_tag(); 150 int xml_start_tag(const char *name, const bool write = true); 151 int xml_end_tag(); 152 153 int xml_attribute(const char *name, const char *fmt, ...) __attribute__ ((format (printf, 2, 3))); 154 155 int xml_newline(); 156 157 int xml_depth(); 158 bool xml_tag_open(); 159 bool xml_root_written(); 160 161 162 char *xml_unescape(const char *str); 163 164 #endif 165 166
