Subject:	macros for sockets?
X-WDR-Disclaimer:	Version $Revision: 1.13 $
X-MIME-Autoconverted:	from quoted-printable to 8bit by delorie.com id QAA20170

I need the following macros defined to compile some low
level libraries that we have.  The two macros that I need are:


SIOCGIFNETMASK & SIOCGIFBRDADDR

from looking at <asm/socket.h> I know they should look like:


#define	SIOCGIFNETMASK	_IOW('s', xx, struct ifreq)  /* get net addr mask */
#define	SIOCGIFBRDADDR	_IOW('s', xx, struct ifreq)   /* get broadcast addr */

but I don't know what xx should be? Can anyone familiar with
the ifreq structure and the _IOW(x, y, z) macro answer these questions?

I would think, given the ifreq structure, at least minimally these should be defined
anyway.

Thanks in advance,
Rand Dvorak
