    Error
In summary, the conversation is about a missing include file, 'unistd.h', and how to fix the error. The speaker suggests checking where the file is located and if it is in one of the include directories. They also mention using Microsoft Visual C++ 6.0 and the error appearing when using the header file. Another person asks why they are using such an old IDE and the speaker admits to not knowing why but mentions buying the program and possibly missing files.

Check where the file is located. Do you have it on disk? In one of include directories? What OS do you use?

What do you need the file for? It appears to be a *nix specific header.

And for that matter, why are you using such an old IDE?
