Hi, can anyone tell me why my cgi script written in C runs perfectly fine in Unix and fails under windows nt?

The cgi prints out an image to the stdio!

Sidefoo, the problems you have is normal!

What happens is that in Unix, the stdio is binary, and in Windows its text.
i.e.  Try the following in Unix and Windows and see what happens:

1)  type picture.gif > picture2.gif (windows)
2)  cat picutre.gif > picture2.gif (Unix)

..see the difference?

to correct that you must convert the std output of windows to binary.

you can accomplish that by simply putting the following line in your code:

setmode (fileio(stdio), O_BINARY);
cout << "Content-type:  image/gif" << endl << endl;

Make sure to check the setmode function out, since I dont have a compiler with me at this time, and I don't remember the exact way to call it.
