You read a GET from the URL, and you read a POST from STDIN. You write the HTML output to STDOUT. You need a routine that parses input, and once you have that written, you're pretty much home free. Interfacing with mySQL is no problem at all. Running Perl or PHP scripts as CGIs means you have to load a mammoth program into memory, then read in the script, then translate the script into instructions which are executed. A program written in a compiled language like C is much smaller, and because it's binary, it starts running immediately. If you aren't sharing your box with anyone else, you can get around that by running Perl or PHP as Apache modules, but in a typical virtual hosting setup, that means setting file permissions wide open, so that any of the hosting company's tens of thousands of users can edit or delete your files. Ouch! The other advantage of a compiled CGI is security. Since you only link in the code to do what you need to do, it's harder for an exploit to get out of hand. That doesn't mean bad programmers with C are going to write secure applications - just that a bad programmer with Perl or PHP is a *real* hazard. I hope you enjoy learning C. Good C programmers tend to be decent at any other language they attempt, because they understand how the machine "thinks" and learn how to organize their work. Try to teach a BASIC programmer Java, or teach a Java programmer COBOL, and they are often hopelessly lost, but a good C programmer is different. deke -- Do gravediggers qualify for "cost of living" raises?
