(Years ago, including 2000 when I bought C99, it was USD 18.) Right now they have both 9899-1999 (C99) and 9899-2011* (C11) which was just adopted (and not yet implemented that I know of) but this probably won't last long. Note you must select the INCITS version; the other (here BSI and ISO/IEC) versions have identical content but are much more costly for legal reasons. (* The ISO/IEC adoption of C11 was very late in the year, and so the INCITS=ANSI=US formal adoption was in 2012. This seems to have resulted in a confusing listing on webstore; the INCITS 2011[2012] link doesn't work and the INCITS 2012 link is 2011.) The committee (formally, Working Group 14 of SubCommittee 22 of ISO/IEC JTC1) website is http://www.open-std.org/jtc1/sc22/wg14/ . They publish numerous working documents, including periodic (usually once or twice a year) updated drafts of the standard, all identified by (roughly) sequential "n" numbers. n869 cited elsethread was indeed the last draft before C99. n1256 was the starting draft for C11, and consisted of C99 as amended by the three Technical Corrigenda and thus is a rather convenient reference to what "C99 really is", except for two minor typos which the editor Lawrence Jones posted to comp.lang.c some years ago but a quick google didn't find. n1570 was the last draft before C11, if you're interested where C may be going (or not) in the future. (Also n1569 nonpublic?) Formally the committee documents are copyright, and years ago they had a statement on the website to the effect they were published "only for purposes advancing standardization of C" or something pretty vague like that, but I find no such statement there now and people in comp.lang.c (and also comp.std.c) have for years frequently cited the standard drafts and sometimes other committee documents and there have never been any complaints about doing so. > Various revisions of POSIX are available free for reference > online; the current POSIX.1-2008 at > http://pubs.opengroup.org/onlinepubs/9699919799/ and the > older POSIX.1-2004 at http://pubs.opengroup.org/onlinepubs/009695399/ > That too. Although POSIX duplicates some information from the C standard(s) but formally says if the POSIX copy differs from the actual C standard the actual C standard prevails. Most of POSIX, of course, is *addditional* to the C standard and in those areas it is definitive. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
