Costello) Newsgroups: comp.unix.bsd.netbsd.misc Subject: sizeof (struct proc) == 256. Why? Date: 13 Jun 1995 17:38:22 -0000 Organization: Washington University, St. Louis MO Lines: 9 Message-ID: <3rkiee$o5i@siesta.cs.wustl.edu> NNTP-Posting-Host: siesta.cs.wustl.edu In NetBSD, sizeof (struct proc) == 256. There is even a p_spare member whose only purpose is to pad the structure up to 256 bytes. What is the reason for this? (I'm hacking the kernel, and might want to add a few members, but I don't want to screw anything up.) Thanks, AMC
