An interface to the Apache <code>ap_log_cerror</code>
function. <var>message</var> is a string with the error message,
<var>level</var> is one of the following flags constants:
<P>
<div class="verbatim"><pre>
APLOG_EMERG
APLOG_ALERT
APLOG_CRIT
APLOG_ERR
APLOG_WARNING
APLOG_NOTICE
APLOG_INFO
APLOG_DEBUG
APLOG_NOERRNO

<P>
If you need to write to log and do not have a reference to a connection or
request object, use the <tt class="function">apache.log_error</tt> function.

<dd>
Reads at most <var>length</var> bytes from the client. The read blocks
indefinitely until there is at least one byte to read. If length is
-1, keep reading until the socket is closed from the other end (This
is known as <code>EXHAUSTIVE</code> mode in the http server code).
<P>
This method should only be used inside <em>Connection Handlers</em>.

<div class="note"><b class="label">Note:</b>
The behaviour of this method has changed since version 3.0.3. In
3.0.3 and prior, this method would block until <var>length</var> bytes
was read.
