Hello Just looking at this page: http://www.kernel.org/doc/man-pages/online/pages/man3/strnlen.3.html It says "This function is a GNU extension." Is strnlen still a GNU only extension? Microsoft and also The Open Group also document this function. http://www.opengroup.org/onlinepubs/9699919799/functions/strlen.html http://msdn.microsoft.com/en-us/library/z50ty2zh%28VS.80%29.aspx Microsoft call it "ANSI" Could strlen page link to strnlen(3) as well please. http://www.kernel.org/doc/man-pages/online/pages/man3/strlen.3.html Likewise, should all four pages refer to each other: wcsnlen wcslen strlen strnlen As there is a string(3) page, should there be a wchar(3) page? Even just a page to collectively refer to other pages. http://www.kernel.org/doc/man-pages/online/pages/man3/string.3.html wchar(3) page could list wcstok wcspbrk(3), wcsrchr(3), wcsstr(3), wmemchr(3) Thank you for taking a look at these. Best regards, Jon p.s. I noticed the http://man7.org/tlpi/TLPI-front-cover.png is very large and slow to load. Also it is 674px à 890px (scaled to 454px à 600px). Reducing it and compressing would save a few seconds off the download! -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
