<br><font size=2 face="sans-serif">I would think a cleaner approach would
be to override the standard message handler to do exactly what you want.
I would start with Clp as part of the unit test overrides the message
handler. Look in Clp/Test at MyMessageHandler.?pp and its use in
unitTest.cpp.</font>

Sbb output with Linux redirect</font></table>

<br>
I am writing a web interface for COIN, specifically for Clp and Sbb.<br>
I want to capture output from these, especially from Sbb. The idea<br>
being folks could "check progress" as the model runs.<br>
<br>
My first attempt was to pause Sbb every x nodes, use methods <br>
to get best solution and current objective, write these to a database,
<br>
then restart. Is it possible to restart sbb after it times out or
reaches<br>
node/solution count?<br>
<br>
My next thought was to just dump all Sbb output to a file, then read and<br>
display the output as it runs. However, I am having major problems<br>
getting output. When I run my application in the backgroud, the<br>
output file is empty until Sbb terminates.<br>
<br>
My app that invokes Sbb is wcSbb.<br>
<br>
I invoke the process as follows:<br>
<br>
nohup /COIN/webCOIN/wcSbb > /COIN/webCOIN/outfiles/myoutfile &<br>
<br>
The process goes to background, but output file is empty until Sbb terminates.<br>
I am on a Redhat box (9.0)<br>
<br>
I get the same thing if I try:<br>
<br>
/COIN/webCOIN/wcSbb > /COIN/webCOIN/outfiles/myoutfile <br>
<br>
I apologize if this turns out to be some linux setting. I just thought
maybe <br>
someone else had encountered it as well.<br>
<br>
Thank you,<br>
<br>
Steve Henderson<br>
