<unistd.h>

Hey all.

I'm trying to include <unistd.h> and the compiler (Visual Studio) claims:
"Error 1 fatal error C1083: Cannot open include file: 'unistd.h': No such file or directory c:\לימודים\c++\avl_try\avl_try\avltree.h 3"

anyone?

Well it isn't a standard file, so I guess your compiler doesn't have it.

You could try commenting out that file, because I'm not entirely sure what could be in unistd.h which an AVL tree implementation might find useful.

Or, if this is someone else's code, have a look around to see if there are any guides for porting this software to different compilers.
