Hi
working with InterMapper (a network tool) on FreeBSD 5.4 I got a
sendmsg -1 errno 22 Invalid argument
I looked in man sendmsg in the errors but I found no EINVAL in the errors.
So I looked at the kernel sources and I found
----------------------------------------------------------------------------------------------------------
static int
sendit(td, s, mp, flags)
register struct thread *td;
int s;
register struct msghdr *mp;
int flags;
{
struct mbuf *control;
struct sockaddr *to;
int error;
if (mp->msg_name != NULL) {
error = getsockaddr(&to, mp->msg_name, mp->msg_namelen);
if (error) {
to = NULL;
goto bad;
}
mp->msg_name = to;
} else {
to = NULL;
}
if (mp->msg_control) {
if (mp->msg_controllen < sizeof(struct cmsghdr)
#ifdef COMPAT_OLDSOCK
&& mp->msg_flags != MSG_COMPAT
#endif
) {
error = EINVAL;
----------------------------------------------------------------------------------------------------------
that error is set to EINVAL so the man page should report EINVAL as possible
error in this funcion.
