在“C/C++”的“请问Unix下编写的CGI（C language）的具体方法，有例子最佳!!!”
有我另一个C的CGI例子。

我挺喜欢用Vc编CGI,
其实CGI就是从标准输入读入，以HTML形式输出到标准输出
//我的几个例子
//处理输入（部分）如果懂CGI一定知道
#include "stdafx.h"
#include <stdio.h>
#include <stdlib.h>
#include <memory.h>
struct Environment{
char *Auth_Password;
char *Auth_Type;
char *Auth_User;
char *Content_Length;
char *Content_Type;
char *Gateway_Interface;
char *HTTP_Accept;
char *HTTP_From;
char *HTTP_Referer;
char *HTTP_User_Agent;
char *Path_Info;
char *Path_Translated;
char *Query_String;
char *Remote_Addr;
char *Remote_Host;
char *Remote_Ident;
char *Remote_User;
char *Remote_Method;
char *Server_Name;
char *Server_Port;
char *Server_Protocol;
char *Server_Software;
char *Script_Name;
char *Server_Admin;
};
void main(void)
{
struct Environment EV;
EV.HTTP_Accept = getenv("HTTP_ACCEPT");
EV.Auth_Password = getenv("AUTH_PASSWORD");
EV.Auth_Type = getenv("AUTH_TYPE");
EV.Auth_User = getenv("AUTH_USER");

EV.Path_Translated = getenv("PATH_TRANSLATED");
EV.Query_String = getenv("QUERY_STRING");
printf("Content-Type: text/html\n\n");

cgi可以用很多语言编写，当然用c或c++编的cgi程序可以在vc6中编译，不存在混合编程。
如果编写IIS下运行的cgi程序，建议该成编写ISAPI Extension 和ISAPI Filter,vc6中有Wizard和例子。
ISAPI是以线程运行的，cgi则是一单独的进程运行，ISAPI比cgi在性能上有极大提高
