The first is to make sure that when +building GnuTLS, the Guile bindings will be installed in the same +place where Guile looks. You may do this by using the +<code>--with-guile-site-dir</code> parameter as follows: +</p> +<div class="example"> +<pre class="example">$ ./configure --with-guile-site-dir=no +</pre></div> + +<p>This will instruct GnuTLS to attempt to install the Guile bindings +where Guile will look for them.

You +need to instruct Guile so that it finds the GnuTLS Guile bindings. +Either use the <code>GUILE_LOAD_PATH</code> environment variable as follows: +</p> +<div class="example"> +<pre class="example">$ GUILE_LOAD_PATH="/usr/local/share/guile/site:$GUILE_LOAD_PATH" guile +scheme@(guile-user)> (use-modules (gnutls)) +scheme@(guile-user)> +</pre></div> + +<p>Alternatively, you can modify Guile’s <code>%load-path</code> variable +(see <a data-manual="guile" href="https://www.gnu.org/software/guile/manual/guile.html#Build-Config">Guile’s run-time options</a> in <cite>The GNU Guile +Reference Manual</cite>). +</p> +<p>At this point, you might get an error regarding +<samp>guile-gnutls-v-2</samp> similar to: +</p> +<div class="example"> +<pre class="example">gnutls.scm:361:1: In procedure dynamic-link in expression (load-extension "guile-gnutls-v-2" "scm_init_gnutls"): +gnutls.scm:361:1: file: "guile-gnutls-v-2", message: "guile-gnutls-v-2.so: cannot open shared object file: No such file or directory" +</pre></div> + +<p>In this case, you will need to modify the run-time linker path, for +example as follows: +</p> +<div class="example"> +<pre class="example">$ LD_LIBRARY_PATH=/usr/local/lib GUILE_LOAD_PATH=/usr/local/share/guile/site guile +scheme@(guile-user)> (use-modules (gnutls)) +scheme@(guile-user)> +</pre></div> + +<p>To check that you got the intended GnuTLS library version, you may +print the version number of the loaded library as follows: +</p> +<div class="example"> +<pre class="example">$ guile +scheme@(guile-user)> (use-modules (gnutls)) +scheme@(guile-user)> (gnutls-version) +"3.7.9" +scheme@(guile-user)> +</pre></div> + + +<hr> +</div> +<div class="chapter" id="Guile-API-Conventions"> +<div class="header"> +<p> +Next: <a href="#Guile-Examples" accesskey="n" rel="next">Guile Examples</a>, Previous: <a href="#Guile-Preparations" accesskey="p" rel="prev">Guile Preparations</a>, Up: <a href="#Top" accesskey="u" rel="up">GnuTLS-Guile</a> [<a href="#SEC_Contents" title="Table of contents" rel="contents">Contents</a>][<a href="#Procedure-Index" title="Index" rel="index">Index</a>]</p> +</div> +<span id="Guile-API-Conventions-1"></span><h2 class="chapter">3 Guile API Conventions</h2> + +<p>This chapter details the conventions used by Guile API, as well as +specificities of the mapping of the C API to Scheme. +</p> + +<ul class="section-toc"> +<li><a href="#Enumerates-and-Constants" accesskey="1">Enumerates and Constants</a></li> +<li><a href="#Procedure-Names" accesskey="2">Procedure Names</a></li> +<li><a href="#Representation-of-Binary-Data" accesskey="3">Representation of Binary Data</a></li> +<li><a href="#Input-and-Output" accesskey="4">Input and Output</a></li> +<li><a href="#Exception-Handling" accesskey="5">Exception Handling</a></li> +</ul> +<hr> +<div class="section" id="Enumerates-and-Constants"> +<div class="header"> +<p> +Next: <a href="#Procedure-Names" accesskey="n" rel="next">Procedure Names</a>, Up: <a href="#Guile-API-Conventions" accesskey="u" rel="up">Guile API Conventions</a> [<a href="#SEC_Contents" title="Table of contents" rel="contents">Contents</a>][<a href="#Procedure-Index" title="Index" rel="index">Index</a>]</p> +</div> +<span id="Enumerates-and-Constants-1"></span><h3 class="section">3.1 Enumerates and Constants</h3> + +<span id="index-enumerate"></span> +<span id="index-constant"></span> + +<p>Lots of enumerates and constants are used in the GnuTLS C API. For +each C enumerate type, a disjoint Scheme type is used—thus, +enumerate values and constants are not represented by Scheme symbols +nor by integers. This makes it impossible to use an enumerate value +of the wrong type on the Scheme side: such errors are automatically +detected by type-checking. +</p> +<p>The enumerate values are bound to variables exported by the +<code>(gnutls)</code> module. These variables +are named according to the following convention: +</p> +<ul> +<li> All variable names are lower-case; the underscore <code>_</code> +character used in the C API is replaced by hyphen <code>-</code>. +</li><li> All variable names are prepended by the name of the enumerate +type and the slash <code>/</code> character. +</li><li> In some cases, the variable name is made more explicit than the +one of the C API, e.g., by avoid abbreviations. +</li></ul> + +<p>Consider for instance this C-side enumerate: +</p> +<div class="example"> +<pre class="example">typedef enum +{ + GNUTLS_CRD_CERTIFICATE = 1, + GNUTLS_CRD_ANON, + GNUTLS_CRD_SRP, + GNUTLS_CRD_PSK +} gnutls_credentials_type_t; +</pre></div> + +<p>The corresponding Scheme values are bound to the following variables +exported by the <code>(gnutls)</code> module: +</p> +<div class="example"> +<pre class="example">credentials/certificate +credentials/anonymous +credentials/srp +credentials/psk +</pre></div> + +<p>Hopefully, most variable names can be deduced from this convention. +</p> +<p>Scheme-side “enumerate” values can be compared using <code>eq?</code> +(see <a data-manual="guile" href="https://www.gnu.org/software/guile/manual/guile.html#Equality">equality predicates</a> in <cite>The GNU Guile Reference +Manual</cite>).

For instance, <code>(cipher->string +cipher/arcfour)</code> yields <code>"ARCFOUR 128"</code>, while +<code>(key-usage->string key-usage/digital-signature)</code> yields +<code>"digital-signature"</code>.

The <code>gnutls_</code> +prefix is always omitted from variable names since a similar effect +can be achieved using Guile’s nifty binding renaming facilities, +should it be needed (see <a data-manual="guile" href="https://www.gnu.org/software/guile/manual/guile.html#Using-Guile-Modules">Using Guile Modules</a> in <cite>The GNU +Guile Reference Manual</cite>). +</p> +<p>Often Scheme procedure names differ from C function names in a way +that makes it clearer what objects they operate on.

+<li> PREAMBLE + +<p>The purpose of this License is to make a manual, textbook, or other +functional and useful document <em>free</em> in the sense of freedom: to +assure everyone the effective freedom to copy and redistribute it, +with or without modifying it, either commercially or noncommercially. +Secondarily, this License preserves for the author and publisher a way +to get credit for their work, while not being considered responsible +for modifications made by others. +</p> +<p>This License is a kind of “copyleft”, which means that derivative +works of the document must themselves be free in the same sense. It +complements the GNU General Public License, which is a copyleft +license designed for free software. +</p> +<p>We have designed this License in order to use it for manuals for free +software, because free software needs free documentation: a free +program should come with manuals providing the same freedoms that the +software does. But this License is not limited to software manuals; +it can be used for any textual work, regardless of subject matter or +whether it is published as a printed book. We recommend this License +principally for works whose purpose is instruction or reference. +</p> +</li><li> APPLICABILITY AND DEFINITIONS + +<p>This License applies to any manual or other work, in any medium, that +contains a notice placed by the copyright holder saying it can be +distributed under the terms of this License. Such a notice grants a +world-wide, royalty-free license, unlimited in duration, to use that +work under the conditions stated herein. The “Document”, below, +refers to any such manual or work. Any member of the public is a +licensee, and is addressed as “you”. You accept the license if you +copy, modify or distribute the work in a way requiring permission +under copyright law. +</p> +<p>A “Modified Version” of the Document means any work containing the +Document or a portion of it, either copied verbatim, or with +modifications and/or translated into another language. +</p> +<p>A “Secondary Section” is a named appendix or a front-matter section +of the Document that deals exclusively with the relationship of the +publishers or authors of the Document to the Document’s overall +subject (or to related matters) and contains nothing that could fall +directly within that overall subject. (Thus, if the Document is in +part a textbook of mathematics, a Secondary Section may not explain +any mathematics.) The relationship could be a matter of historical +connection with the subject or with related matters, or of legal, +commercial, philosophical, ethical or political position regarding +them. +</p> +<p>The “Invariant Sections” are certain Secondary Sections whose titles +are designated, as being those of Invariant Sections, in the notice +that says that the Document is released under this License. If a +section does not fit the above definition of Secondary then it is not +allowed to be designated as Invariant. The Document may contain zero +Invariant Sections. If the Document does not identify any Invariant +Sections then there are none. +</p> +<p>The “Cover Texts” are certain short passages of text that are listed, +as Front-Cover Texts or Back-Cover Texts, in the notice that says that +the Document is released under this License. A Front-Cover Text may +be at most 5 words, and a Back-Cover Text may be at most 25 words. +</p> +<p>A “Transparent” copy of the Document means a machine-readable copy, +represented in a format whose specification is available to the +general public, that is suitable for revising the document +straightforwardly with generic text editors or (for images composed of +pixels) generic paint programs or (for drawings) some widely available +drawing editor, and that is suitable for input to text formatters or +for automatic translation to a variety of formats suitable for input +to text formatters. A copy made in an otherwise Transparent file +format whose markup, or absence of markup, has been arranged to thwart +or discourage subsequent modification by readers is not Transparent. +An image format is not Transparent if used for any substantial amount +of text. A copy that is not “Transparent” is called “Opaque”. +</p> +<p>Examples of suitable formats for Transparent copies include plain +ASCII without markup, Texinfo input format, LaTeX input +format, SGML or XML using a publicly available +DTD, and standard-conforming simple HTML, +PostScript or PDF designed for human modification. Examples +of transparent image formats include PNG, XCF and +JPG. Opaque formats include proprietary formats that can be +read and edited only by proprietary word processors, SGML or +XML for which the DTD and/or processing tools are +not generally available, and the machine-generated HTML, +PostScript or PDF produced by some word processors for +output purposes only. +</p> +<p>The “Title Page” means, for a printed book, the title page itself, +plus such following pages as are needed to hold, legibly, the material +this License requires to appear in the title page. For works in +formats which do not have any title page as such, “Title Page” means +the text near the most prominent appearance of the work’s title, +preceding the beginning of the body of the text. +</p> +<p>The “publisher” means any person or entity that distributes copies +of the Document to the public. +</p> +<p>A section “Entitled XYZ” means a named subunit of the Document whose +title either is precisely XYZ or contains XYZ in parentheses following +text that translates XYZ in another language. (Here XYZ stands for a +specific section name mentioned below, such as “Acknowledgements”, +“Dedications”, “Endorsements”, or “History”.) To “Preserve the Title” +of such a section when you modify the Document means that it remains a +section “Entitled XYZ” according to this definition. +</p> +<p>The Document may include Warranty Disclaimers next to the notice which +states that this License applies to the Document. These Warranty +Disclaimers are considered to be included by reference in this +License, but only as regards disclaiming warranties: any other +implication that these Warranty Disclaimers may have is void and has +no effect on the meaning of this License. +</p> +</li><li> VERBATIM COPYING + +<p>You may copy and distribute the Document in any medium, either +commercially or noncommercially, provided that this License, the +copyright notices, and the license notice saying this License applies +to the Document are reproduced in all copies, and that you add no other +conditions whatsoever to those of this License. You may not use +technical measures to obstruct or control the reading or further +copying of the copies you make or distribute. However, you may accept +compensation in exchange for copies. If you distribute a large enough +number of copies you must also follow the conditions in section 3. +</p> +<p>You may also lend copies, under the same conditions stated above, and +you may publicly display copies. +</p> +</li><li> COPYING IN QUANTITY + +<p>If you publish printed copies (or copies in media that commonly have +printed covers) of the Document, numbering more than 100, and the +Document’s license notice requires Cover Texts, you must enclose the +copies in covers that carry, clearly and legibly, all these Cover +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on +the back cover. Both covers must also clearly and legibly identify +you as the publisher of these copies. The front cover must present +the full title with all words of the title equally prominent and +visible. You may add other material on the covers in addition. +Copying with changes limited to the covers, as long as they preserve +the title of the Document and satisfy these conditions, can be treated +as verbatim copying in other respects. +</p> +<p>If the required texts for either cover are too voluminous to fit +legibly, you should put the first ones listed (as many as fit +reasonably) on the actual cover, and continue the rest onto adjacent +pages. +</p> +<p>If you publish or distribute Opaque copies of the Document numbering +more than 100, you must either include a machine-readable Transparent +copy along with each Opaque copy, or state in or with each Opaque copy +a computer-network location from which the general network-using +public has access to download using public-standard network protocols +a complete Transparent copy of the Document, free of added material. +If you use the latter option, you must take reasonably prudent steps, +when you begin distribution of Opaque copies in quantity, to ensure +that this Transparent copy will remain thus accessible at the stated +location until at least one year after the last time you distribute an +Opaque copy (directly or through your agents or retailers) of that +edition to the public. +</p> +<p>It is requested, but not required, that you contact the authors of the +Document well before redistributing any large number of copies, to give +them a chance to provide you with an updated version of the Document. +</p> +</li><li> MODIFICATIONS + +<p>You may copy and distribute a Modified Version of the Document under +the conditions of sections 2 and 3 above, provided that you release +the Modified Version under precisely this License, with the Modified +Version filling the role of the Document, thus licensing distribution +and modification of the Modified Version to whoever possesses a copy +of it. In addition, you must do these things in the Modified Version: +</p> +<ol type="A" start="1"> +<li> Use in the Title Page (and on the covers, if any) a title distinct +from that of the Document, and from those of previous versions +(which should, if there were any, be listed in the History section +of the Document). You may use the same title as a previous version +if the original publisher of that version gives permission. + +</li><li> List on the Title Page, as authors, one or more persons or entities +responsible for authorship of the modifications in the Modified +Version, together with at least five of the principal authors of the +Document (all of its principal authors, if it has fewer than five), +unless they release you from this requirement. + +</li><li> State on the Title page the name of the publisher of the +Modified Version, as the publisher. + +</li><li> Preserve all the copyright notices of the Document. + +</li><li> Add an appropriate copyright notice for your modifications +adjacent to the other copyright notices. + +</li><li> Include, immediately after the copyright notices, a license notice +giving the public permission to use the Modified Version under the +terms of this License, in the form shown in the Addendum below. + +</li><li> Preserve in that license notice the full lists of Invariant Sections +and required Cover Texts given in the Document’s license notice. + +</li><li> Include an unaltered copy of this License. + +</li><li> Preserve the section Entitled “History”, Preserve its Title, and add +to it an item stating at least the title, year, new authors, and +publisher of the Modified Version as given on the Title Page. If +there is no section Entitled “History” in the Document, create one +stating the title, year, authors, and publisher of the Document as +given on its Title Page, then add an item describing the Modified +Version as stated in the previous sentence. + +</li><li> Preserve the network location, if any, given in the Document for +public access to a Transparent copy of the Document, and likewise +the network locations given in the Document for previous versions +it was based on. These may be placed in the “History” section. +You may omit a network location for a work that was published at +least four years before the Document itself, or if the original +publisher of the version it refers to gives permission. + +</li><li> For any section Entitled “Acknowledgements” or “Dedications”, Preserve +the Title of the section, and preserve in the section all the +substance and tone of each of the contributor acknowledgements and/or +dedications given therein. + +</li><li> Preserve all the Invariant Sections of the Document, +unaltered in their text and in their titles. Section numbers +or the equivalent are not considered part of the section titles. + +</li><li> Delete any section Entitled “Endorsements”. Such a section +may not be included in the Modified Version. + +</li><li> Do not retitle any existing section to be Entitled “Endorsements” or +to conflict in title with any Invariant Section. + +</li><li> Preserve any Warranty Disclaimers. +</li></ol> + +<p>If the Modified Version includes new front-matter sections or +appendices that qualify as Secondary Sections and contain no material +copied from the Document, you may at your option designate some or all +of these sections as invariant. To do this, add their titles to the +list of Invariant Sections in the Modified Version’s license notice. +These titles must be distinct from any other section titles. +</p> +<p>You may add a section Entitled “Endorsements”, provided it contains +nothing but endorsements of your Modified Version by various +parties—for example, statements of peer review or that the text has +been approved by an organization as the authoritative definition of a +standard. +</p> +<p>You may add a passage of up to five words as a Front-Cover Text, and a +passage of up to 25 words as a Back-Cover Text, to the end of the list +of Cover Texts in the Modified Version. Only one passage of +Front-Cover Text and one of Back-Cover Text may be added by (or +through arrangements made by) any one entity. If the Document already +includes a cover text for the same cover, previously added by you or +by arrangement made by the same entity you are acting on behalf of, +you may not add another; but you may replace the old one, on explicit +permission from the previous publisher that added the old one. +</p> +<p>The author(s) and publisher(s) of the Document do not by this License +give permission to use their names for publicity for or to assert or +imply endorsement of any Modified Version. +</p> +</li><li> COMBINING DOCUMENTS + +<p>You may combine the Document with other documents released under this +License, under the terms defined in section 4 above for modified +versions, provided that you include in the combination all of the +Invariant Sections of all of the original documents, unmodified, and +list them all as Invariant Sections of your combined work in its +license notice, and that you preserve all their Warranty Disclaimers. +</p> +<p>The combined work need only contain one copy of this License, and +multiple identical Invariant Sections may be replaced with a single +copy. If there are multiple Invariant Sections with the same name but +different contents, make the title of each such section unique by +adding at the end of it, in parentheses, the name of the original +author or publisher of that section if known, or else a unique number. +Make the same adjustment to the section titles in the list of +Invariant Sections in the license notice of the combined work. +</p> +<p>In the combination, you must combine any sections Entitled “History” +in the various original documents, forming one section Entitled +“History”; likewise combine any sections Entitled “Acknowledgements”, +and any sections Entitled “Dedications”. You must delete all +sections Entitled “Endorsements.” +</p> +</li><li> COLLECTIONS OF DOCUMENTS + +<p>You may make a collection consisting of the Document and other documents +released under this License, and replace the individual copies of this +License in the various documents with a single copy that is included in +the collection, provided that you follow the rules of this License for +verbatim copying of each of the documents in all other respects. +</p> +<p>You may extract a single document from such a collection, and distribute +it individually under this License, provided you insert a copy of this +License into the extracted document, and follow this License in all +other respects regarding verbatim copying of that document. +</p> +</li><li> AGGREGATION WITH INDEPENDENT WORKS + +<p>A compilation of the Document or its derivatives with other separate +and independent documents or works, in or on a volume of a storage or +distribution medium, is called an “aggregate” if the copyright +resulting from the compilation is not used to limit the legal rights +of the compilation’s users beyond what the individual works permit. +When the Document is included in an aggregate, this License does not +apply to the other works in the aggregate which are not themselves +derivative works of the Document. +</p> +<p>If the Cover Text requirement of section 3 is applicable to these +copies of the Document, then if the Document is less than one half of +the entire aggregate, the Document’s Cover Texts may be placed on +covers that bracket the Document within the aggregate, or the +electronic equivalent of covers if the Document is in electronic form. +Otherwise they must appear on printed covers that bracket the whole +aggregate. +</p> +</li><li> TRANSLATION + +<p>Translation is considered a kind of modification, so you may +distribute translations of the Document under the terms of section 4. +Replacing Invariant Sections with translations requires special +permission from their copyright holders, but you may include +translations of some or all Invariant Sections in addition to the +original versions of these Invariant Sections. You may include a +translation of this License, and all the license notices in the +Document, and any Warranty Disclaimers, provided that you also include +the original English version of this License and the original versions +of those notices and disclaimers. In case of a disagreement between +the translation and the original version of this License or a notice +or disclaimer, the original version will prevail. +</p> +<p>If a section in the Document is Entitled “Acknowledgements”, +“Dedications”, or “History”, the requirement (section 4) to Preserve +its Title (section 1) will typically require changing the actual +title. +</p> +</li><li> TERMINATION + +<p>You may not copy, modify, sublicense, or distribute the Document +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense, or distribute it is void, and +will automatically terminate your rights under this License. +</p> +<p>However, if you cease all violation of this License, then your license +from a particular copyright holder is reinstated (a) provisionally, +unless and until the copyright holder explicitly and finally +terminates your license, and (b) permanently, if the copyright holder +fails to notify you of the violation by some reasonable means prior to +60 days after the cessation. +</p> +<p>Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. +</p> +<p>Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, receipt of a copy of some or all of the same material does +not give you any rights to use it. +</p> +</li><li> FUTURE REVISIONS OF THIS LICENSE + +<p>The Free Software Foundation may publish new, revised versions +of the GNU Free Documentation License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. See +<a href="https://www.gnu.org/licenses/">https://www.gnu.org/licenses/</a>. +</p> +<p>Each version of the License is given a distinguishing version number. +If the Document specifies that a particular numbered version of this +License “or any later version” applies to it, you have the option of +following the terms and conditions either of that specified version or +of any later version that has been published (not as a draft) by the +Free Software Foundation. If the Document does not specify a version +number of this License, you may choose any version ever published (not +as a draft) by the Free Software Foundation. If the Document +specifies that a proxy can decide which future versions of this +License can be used, that proxy’s public statement of acceptance of a +version permanently authorizes you to choose that version for the +Document. +</p> +</li><li> RELICENSING + +<p>“Massive Multiauthor Collaboration Site” (or “MMC Site”) means any +World Wide Web server that publishes copyrightable works and also +provides prominent facilities for anybody to edit those works. A +public wiki that anybody can edit is an example of such a server. A +“Massive Multiauthor Collaboration” (or “MMC”) contained in the +site means any set of copyrightable works thus published on the MMC +site. +</p> +<p>“CC-BY-SA” means the Creative Commons Attribution-Share Alike 3.0 +license published by Creative Commons Corporation, a not-for-profit +corporation with a principal place of business in San Francisco, +California, as well as future copyleft versions of that license +published by that same organization. +</p> +<p>“Incorporate” means to publish or republish a Document, in whole or +in part, as part of another Document. +</p> +<p>An MMC is “eligible for relicensing” if it is licensed under this +License, and if all works that were first published under this License +somewhere other than this MMC, and subsequently incorporated in whole +or in part into the MMC, (1) had no cover texts or invariant sections, +and (2) were thus incorporated prior to November 1, 2008. +</p> +<p>The operator of an MMC Site may republish an MMC contained in the site +under CC-BY-SA on the same site at any time before August 1, 2009, +provided the MMC is eligible for relicensing. +</p> +</li></ol> + +<span id="ADDENDUM_003a-How-to-use-this-License-for-your-documents"></span><h3 class="heading">ADDENDUM: How to use this License for your documents</h3> + +<p>To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and +license notices just after the title page: +</p> +<div class="example"> +<pre class="example"> Copyright (C) <var>year</var> <var>your name</var>. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.3 + or any later version published by the Free Software Foundation; + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover + Texts.
