Guy, thanks for clarifying,

please see http://leaf.dragonflybsd.org/~swildner/ioccom.diff, which
adjusts our code to this intention (include <sys/ioccom.h> only in
headers where ioctl codes are defined).

If no one objects, I'll commit it tomorrow or Thursday.


One other thing that came to mind, though - there's no (non-obsolete) UN*X standard for what to include to get ioctl() declared. The Single UNIX Specification only mentions ioctl() in order to support some STREAMS stuff, so they declared it in some STREAMS header file - not very useful for non-STREAMS devices - and that's now obsolete in the current SUS. I think all the BSDs say that you include <sys/ioctl.h> to declare it (Mac OS X does).

I might be tempted to move the declaration of ioctl() to sys/ioccom.h as well; you could then still include <sys/ioctl.h> to get it declared, but you also get it declared if you include some header that includes <sys/ioccom.h> and declares ioctls.
