David,<br>
|
|
<p>
|
|
Can you explain this to me:<br>
|
|
<p>
|
|
<p>
|
|
nread = read (s->pipe, buf, max_len);<br>
|
|
DBG(3, "read %ld bytes\n", (long) nread);<br>
|
|
<p>
|
|
if (!s->scanning)<br>
|
|
return do_stop (s);<br>
|
|
<p>
|
|
<p>
|
|
Why do you first try to read data from the pipe, and only then <br>
|
|
do the check for s->scanning? When would s->scanning get changed?<br>
|
|
<p>
|
|
If s->scanning is false, why would you still need to "do_stop"?<br>
|
|
<p>
|
|
Roger.<br>
