Subject: Xterm -S & PTY problem
Date: 22 Feb 1999 10:09:57 GMT
Hi.
I'm trying to use "xterm -S" for input/otput from my program.
After everything's set I'm able to write to an xterm from
my PTY MASTER process, but I can't read anything that is typed
in xterm window. Here's the source :
fd = open("/dev/ptyze", O_RDWR | O_NDELAY, 00666);
tcgetattr(fd, &term_data);
term_data.c_lflag &= ~ICANON;
//term_data.c_lflag &= ~ECHO;
term_data.c_cflag &= CREAD;
term_data.c_cc[VTIME] = 0;
term_data.c_cc[VMIN] = 1;
tcsetattr(fd,TCSANOW,&term_data);
sprintf(tmp_str, "xterm -Sze%d", fd);
pid = fork();
if (pid == 0) {
execl("/bin/sh", "/bin/sh", "-c", tmp_str, NULL);
}
FD_ZERO(&rfds);
FD_SET(fd, &rfds);
tv.tv_sec = 5;
tv.tv_usec = 0;
res = select(fd, &rfds, NULL, NULL, &tv);
if ((res != -1) && (res != 0))
puts("Got data");
else
puts("fuck, no data");
Any1 can help ?

hi,
How can two drivers communicate between each other in Linux?
Does Linux support some sort of Inter Driver Communication (IDC) ???
Any info would be greatly appreciated!

Hello all!
Are there any good documentation on Linux ioctl() requests
*other than* kernel source? Descriptions in man pages are so
brief as to understand the functionality of particular requests.
Thanks in advance,

This *is* ridiculous.
I can see why someone might want to use __setfpucw() (although that
reason disappears if fesetenv() and friends were available in glibc-2.0;
I can't remember); but what possible reason would an application
developer have for calling __libc_init()? It's about as useful as the
init syscall is to userspace people.

Suggestion: Add a little thing in so that if configure hasn't been run

My card wasnt supported under Redhat 5.1, but finally, there was a driver
under 5.2. Sometimes X just shuts down and leaves a message like
AmSync() (or something like that). I have to reboot to start X after this.
I cant find any other drivers supporting my cards chipset.
Any ideas?
(I probably should get a new graphics card)

go back and read the original posting. that first sentence just
rambles on and on and on...and never seems to want to get to a full
stop and go on to the next sentence.
in case you can't find it, for a typical example go to
<URL:http://www.kelleys.org/mhomes/>
and visit the `mailbag'. about mid way down there's a letter which
begins
`Dear Doug, The Lord Jesus Christ, God your Creator in human form, was
despised, rejected, mocked and....'
and proceeds to ramble on for a hundred or more words. you can't be a
`*real* christian [tm]' unless you start all your letters like this.
another thing that makes a person a *real* christian is to speak in
that `*real* christian soothing soft voice [tm]'. you know the one,
where the person won't raise their voice but goes on and on in a silky
monotone. makes me want to slug them right in the old kisser - and
i'm normally not a violent man! it's like dammit, just speak like a
normal human being. and these mock gay people for their
affectations. what a laugh.

AFAIK gdb supports debugging threads. Didnt test it much though,

I had the same problem - bought what I thought was a real modem only to
realise it was a winmodem three months later. The shop I bought it from
wouldn't give me a refund, but they did offer to sell me a rather nice
external at trade price, and I then sold my winmodem on.... I think I made
a profit :-) Of course you might not be so lucky, but it's worth talking
to the people in the shop and seeing if they'll help you out (you could
quote the trade descriptions act at them, but I found it more helpful to
describe the problem and reason with them).
Good luck :-)

It probably has the old POWER chipset - AIR, 560's were quite early
RS/6000's.
And I have no idea how compatible POWER is with the PowerPC chip, but
I'll bet it isn't very.

I should imagine that your best source of recourse would be to go to
the supplier from whom you bought the modem. I would hope that,
assuming the modem is still in original condition, they would be
prepared to make a suitable substitution, in return for the difference
in price, since they failed to describe the goods correctly. If they
won't, then name and shame the bastards, especially if it was that
gottverdammt Time Computers, whom I wouldn't trust to sell a mousemat
without screwing the order up somehow.
An important thing: did they simply fail to tell you it was a
winmodem, or did you ask and were told that it was *not* a winmodem?
I'm afraid "caveat emptor" very much applies if you bought the modem
but did not explicitly request a non-winmodem, but if you asked and
they told you - even verbally - that the modem was a non-winmodem,
then the Sale of Goods Act comes into play, and you have a theoretical
case against them.
If you didn't ask, and no representations were made by them, then - in
law - you have no recourse, and I'd stick to asking very nicely if
they'll change it for you. In fact, ask very nicely anyway!
Good luck.

Subject: sound card IRQ conflict
Date: Mon, 22 Feb 1999 13:23:18 -0500
I have an embedded Creative/Ensoniq PCI sound card. When I checked the
IRQ assignments in Windows there were 4 devices (including the sound
card) using IRQ channel 11. I tried changing the channel for the sound
card, but Win 98 will not allow it. In linux (RH 5.2) at boot-up and
afterwards the system sees the device as busy. As a result, I have no
sound in linux. Any suggestions as to how I might get it to work?

All directory access functions like opendir(), readdir() and
so on are part of the C library on Linux and see dirent.h
for more. Other systems come with ndir.h but in your case, no,
forget about it. It's just autoconf must take care of all the
little differences that still exist.
