@ -361,24 +361,6 @@ standard wanted to change it into a \fIsize_t *\fP, and that is what it is
for SunOS 5.
Later POSIX drafts have \fIsocklen_t *\fP,
and so do the Single UNIX Specification and glibc2.
Quoting Linus Torvalds:
.\" .I fails: only italicizes a single line
"_Any_ sane library _must_ have "socklen_t" be the same size
as int.
Anything else breaks any BSD socket layer stuff.
POSIX initially \fIdid\fP make it a size_t, and I (and hopefully others, but
obviously not too many) complained to them very loudly indeed.
Making it a size_t is completely broken, exactly because size_t very
seldom is the same size as "int" on 64-bit architectures, for example.
And it
\fIhas\fP to be the same size as "int" because that's what the BSD socket
interface is.
Anyway, the POSIX people eventually got a clue, and created "socklen_t".
They shouldn't have touched it in the first place, but once they did
they felt it had to have a named type for some unfathomable reason
(probably somebody didn't like losing face over having done the original
stupid thing, so they silently just renamed their blunder)."
