[S.u.S.E. Linux] stropts.h ??

I am trying to compile the examples from W. Richard Stevens' book. During the compilation, I got an error message saying: ptyopen.c:5: stropts.h: No such file or directory I find that there is no stropts.h on my machine. Can someone tell me how to get around this in Linux? I know this file exists on the AIX machines and SGI machines. Any help will be greatly appreciated. Thank you. Regards, C. J.
