At some point, probably between NetBSD 0.8 and 0.9 (and 4.3 and 4.4?),
the sockaddr_* structures changed to have to fields u_char s*_len and
s*_family instead of u_short s*_family.
Can someone tell me what the purpose of this change is and how user
code should be changed? Code that passes
sizeof(a.sun_family)+strlen(a.sun_path)
as the namelen argument to bind will no longer work (and this is what
the NetBSD IPC tutorial tells you to do!). What should be used instead?
sizeof(a)? sizeof(a) - sizeof(a.sun_path) + strlen(a.sun_path)?
offsetof(a, sun_path) + strlen(a.sun_path)?
