ioctl serial port and SIOCGSTAMP

[lhommedumatch]

Hi,
Does the ioctl(fd,SIOCGS TAMP,&time_val) function work for serial port?
(fd = open("/dev/ttyS1",O_RDWR))

Regards,

Is anyone else getting the feeling that there are suddenly a lot of
very specific off-topic questions in this group ?

Offhand, the questions sound like they're copied from some FAQ list,
perhaps the comp.unix.progr ammer one, even.

SIOCGSTAMP does not appear to be part of Unix. It appears to
be primarily Linux.

I can't imagine so! The clue is in the question: SIOCGSTAMP is a
*socket IO control* request, giving you access to timestamp information
for a packet. What would it even mean for a serial device?

Are you joking? Do you honestly believe a question as bizarre as the
OP's is frequently asked? I'd be surprised if it's ever occurred to
anyone ever before.

c.u.p is a very tolerant group!

Perhaps it has to do with the fact that a certain recent regular here
(I don't want to criticize Walter Roberson by mentioning his name) has
made a habit of answering many off-topic questions if they relate to
*NIX systems.

"recent regular"? I've been a regular poster here since February 2005.

Well, that is an interesting hypothesis, but I don't think it is
supportable with very much in the way of facts and statistics.

For example, there have been quite a number of questions about
sockets recently; could you point to any of my comp.lang.c
postings that have provided more than a very basic hint about
socket programming? And then compare that to the number of times
I have said something similar to,

The C standards do not know anything about networking, let alone
NAT. Networking matters are platform dependant. You should ask
in a development newsgroup that supports your operating system.
Perhaps you became confused by a couple of my recent postings in which
I posted SGI IRIX specific answers in an effort to demonstrate concretely
to the OP that they question they asked truly was system dependant
and that the answer for one system was likely to be completely
useless for other systems. I am certainly not the only regular who
sometimes answers questions with correct but system-dependant
information (often for an obscure platform) as a didactic tool
to demonstrate a point.
