How can I use c++ for CGI? What do I need and how do I set it up?

Thanks, max. Shoulda tried google first.

I have another problem.

I'm trying to get the length for the environment variable but I keep getting a segmentation fault. Here's the code:

main()

{

  const char *length1 = getenv("CONTENT_LENGTH");



  cout << *length1;

}

quote:

---

const char *length1 = getenv("CONTENT_LENGTH");

---

ouch!

are you sure that "CONTENT_LENGTH" is set? if not and is returning a NULL, then trying to read from that address will crash your program.

try printf() , i remember it prints a string of it exists, or a NULL if a null pointer was provided.

printf("%s\n", length1);

gl,

Thanks, lallous. Yeah, it was trying to read a NULL address. So how do I check if CONTENT_LENGTH is set, or set it?
