cgiInit(3)


NAME

   cgiInit - Initializes CGI library

SYNOPSYS

   #include <cgi.h>

   s_cgi *cgiInit ();

DESCRIPTION

   This  routine  initializes  the  CGI  routines.  Mainly it reads in and
   decodes CGI data for later processing.  If the program  is  not  called
   via CGI interface the user is prompted to type in CGI variable bindings
   via stdin - just like CGI.pm does.  There is no limit in the number  of
   variable bindings.

   If  HTTP  Cookies  are  used  (through  the  variable HTTP_COOKIE) this
   routine will parse them as well and assign them to internal  variables.
   There is no limit in the number of cookies.

   To  set  a cookie you'll have to use the cgiSetHeader(3) routine.  Some
   clients allow 4kB of Cookies while others only allow short ones.   Some
   clients may also allow only 200 Cookies for a certain domain/path pair.

   This  routine  normally is the first or second that is called from this
   library.  Only cgiDebug()  may  be  called  before.   If  debugging  is
   enabled this routine produces some additional output.

   The  library  supports both the regular GET and POST methods as well as
   multipart/form-data.

   Memory allocated by this library is freed with the cgiFree(3) function.

RETURN VALUE

   On success a set of CGI variable bindings is returned  that  is  needed
   for later processing.  If an error occurs NULL is returned.

   This  CGI library is written by Martin Schulze <joey@infodrom.org>.  If

Opportunity


Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.



Free Software


Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.

Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.



Free Books


The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.

Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.



Education


Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.

Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
