writing cgi using C++

Posts: 59
Hi
I'm writing a C++ program to run it as cgi. I need to receive input, and as I've found out looking up the net, the most fundamental way is to use getenv() from cstdlib.h.
I wanna know if there's any other interface to receiving environment variables, that is made for C++, I mean I look for equivalent of cstdlib.h in C++, IF EXISTS AT ALL.
Thanks.

The system call interface to any CGI program/script is the same no matter the language the CGI was written in. This is documented in the HTML standards. You just need for your C/C++ program to process the passed arguments appropriately.0 -

I do not know much about this matter (if anything at all).
Do you have any link where I could get introduced to all this CGI world?
Thanks woboyle!

Rubberman, what do you mean by that?
Receiving GET data is as simple as using getenv("QUERY_STRING") , kid's stuff, but I need to handle much bigger data and therefore I have to use ... POST! you know.
Please tell me clearly what should I do to receive post data?
And also, I asked if there's any library that can be used instead of <stdlib.h> and is not based on <stdlib.h>.0 -
I believe that the POST data is passed to the stdin of the CGI program.0

Great!
Well, do you "believe" that data is passed through stdin, or you're exactly 100% certain?
And also, Rubberman, would you please tell me how to capture it?

Thanks jabirali,
Considering the fact that I've first explored the net and then picked the pen to weave a thread in forum, I already know that, and I've already used the most common methods of receiving data from cin, such as << and get(), but I know that here's something I don't know, say another member function of cin or something like that, that I don't know and is the key for me to going ahead.
Most of the resources on the net are writing perl programs as CGI and rarely I can find some "useful" page on net to have talked about writing CGI using C++ and thus discussing the most common problems.
I'll keep searching and trying other resources.
But thanks anyway ;-)0 -
Have you tried doing something like this?
#include <iostream> #include <sstream> #include <string> using namespace std; int main() { stringstream ss; ss << cin.rdbuf(); cout << "Content-type: text/html\\n\\n<html><body>\\n" << "Data received:\\n" << ss.str() << "\\n</body></html>\\n"; return 0; }
