I'm trying to write a client for a socket program in c++ to be compiled and run on UNIX. To test it out, I have been trying to connect to various webpages and simply print the html code to the screen. The problem that I'm running into is that I'm butting up against the maximum number of bytes that can be crammed into a packet. That's to say... some of the webpages that I try to look at are too large to fit into one packet. Is there a way to recieve multiple packets from a server? To this point, I have been able to connect to the server, send the request, and do a 'recv()'. Is there a way to recieve more than one packet? Thank you very much, Ben Back to top Jack Klein Guest Posted: Sat Sep 11, 2004 3:31 am    Post subject: Re: Socket Client recieving Multiple Packets On 10 Sep 2004 18:32:39 -0700, [email]bwilde (AT) gmail (DOT) com[/email] (Ben) wrote in comp.lang.c++: Quote: Hello all, I've got a fairly specific problem, and I'm hoping that somebody will have had to do something similar in the past and can help me out.

Thank you very much, Ben The C++ language has no sockets, no support for networking at all in fact. All such features are platform-specific extensions, not a part of the language. You need to take this to news:comp.unix.programmer, but read their socket FAQ first. -- Jack Klein Home: http://JK-Technology.Com FAQs for comp.lang.c http://www.eskimo.com/~scs/C-faq/top.html comp.lang.c++ http://www.parashift.com/c++-faq-lite/ alt.comp.lang.learn.c-c++ http://www.contrib.andrew.cmu.edu/~ajo/docs/FAQ-acllc.html Back to top Karl Zimmerman Guest Posted: Mon Sep 27, 2004 7:08 am    Post subject: Re: Socket Client recieving Multiple Packets In article <dae9916a.0409101732.145ea35a (AT) posting (DOT) google.com>, [email]bwilde (AT) gmail (DOT) com[/email] (Ben) wrote: Quote: I'm trying to write a client for a socket program in c++ to be compiled and run on UNIX.

Jack is right, this is a platform-related question; but the short answer is "yes; do multiple calls to 'recv()' (or 'read()')". Note that different session-layer protocols (like HTTP) have different rules on how to tell you have read all of the data you can expect; you'll have to read the HTTP RFC in order to get full details, but a short-short answer is, you're done when (a) the connection closes (recv/read will fail), or (b) you've read the number of bytes indicated in the Content-Length: header, or (c) you've read the last "chunk" of a chunk-encoded page. -- Karl Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         C++Talk.NET Forum Index -> C++ language (comp.lang.c++) All times are GMT Page 1 of 1   Jump to: Select a forum C/C++----------------C LanguageC Language (Moderated)C++ Language (Moderated)C++ language (comp.lang.c++)C++ language, library and standards Non-English C/C++ Newsgroups----------------C++ (German)C++ (French)  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
