hi folks,
i've figured out how to start BigClock on my audrey from a remote location:
run "http://audreygraphite.steeve.home/BigClock.shtml?1" from any browser. it works. fires up BigClock. Now, how do i turn it off? i've tried "http://audreygraphite.steeve.home/BigClock.shtml?0"...no go. any ideas, anybody?
Oh, i should say this: i had to create an executable .shtml file called "BigClock.shtml". It's content is:

<html><head><title>Shell</title></head><body>
<!--#exec cmd="/nto/bin/BigClock -a 0x40010004 -b6 -m3 -s$QUERY_STRING" -->
</body></html>

Basically, the above command is a direct copy of D. Davis' gpio command:

<html><head><title>Shell</title></head><body>
<!--#exec cmd="/kojak/gpio -a 0x40010004 -b6 -m3 -s$QUERY_STRING" -->
</body></html>

I just changed things so that the command would run BigClock.

What you want to do is execute a script which finds the process ID of BigClock and then kills it. I don't think BigClock is actually paying any attention to the -s$QUERY_STRING command-ling switch - which your page is passing as -s1.

I don't have my Audreys set up here at the new house, and my QNX is rusty, otherwise I would help more.

Here's an idea... I haven't tried this myself just yet, but I'm pretty certain it would work.

Create 2 scripts - startbigclock and killbigclock

In startbigclock, do

#!/bin/ksh
/nto/bin/BigClock -a 0x40010004 -b6 -m3
echo "$!" >/tmp/bigclock.pid

and in killbigclock, do

pid=`cat /tmp/bigclock.pid`
kill $pid
rm /tmp/bigclock.pid

Note : It's critical to use ` <--- backticks on the pid=... line. That will substitute the content of the file into the pid variable.

So, in a nutshell, save the process id of bigblock, and then retrieve it and kill it. All you need is to make your web scripts invoke startbigclock and killbigclock and you're off to the races.

Let me know if that works out for you.

Instead of saving off the pid, why not use slay:

slay -f BigClock

(see http://www.qnx.com/developer/docs/qnx_4.25_docs/qnx4/utils/s/slay.html)

Try reading up on the SSI at http://www.qnx.com/developer/docs/qnx_6.1_docs/neutrino/utilities/s/slinger.html#syntax

I think this should work in your page:

<html>
<head>
<title>Shell</title>
</head>
<body>

<!--#if "$QUERY_STRING" == "1" goto startclock -->
<!--#if "$QUERY_STRING" == "0" goto stopclock -->
<!--#goto ="done" -->

<!--#label ="startclock" -->
<!--#exec cmd="/nto/bin/BigClock" -->
Clock Started
<!--#goto ="done" -->

<!--#label ="stopclock" -->
<!--#exec cmd="slay -f BigClock" -->
Clock Stopped
<!--#goto ="done" -->

<!--#label ="nothingpassed" -->
Nothing was Passed

<!--#label ="done" -->
Done

</body>
</html>

"Instead of saving off the pid, why not use slay:"

Why, because that's way too simple. :)

Good call, I'd tried killall, didn't know about slay... I'm an Audrey and QNX newbie (but an old unix hack...)

When calling from a browser with...
http://192.168.1.3/runprog.shtml?1


Why would this work...
<html><head><title>runprog</title></head>
<!--#exec cmd="/nto/photon/bin/keyboard" -->
</body></html>


But this NOT WORK...
<html><head><title>runprog</title></head>
<!--#exec cmd="/nto/bin/shutdown" -->
</body></html>

Anyone got any idea?

I've got a simple question for this thread.
Where can I find BigClock?
The only other thread mentioning it has a bad link.

Thanks in advance.
