Low level read from the channel. This function may block until the requested number of characters were read or the read timeout was reached. The <a class="el" href="classPChannel.html#z49_3">GetLastReadCount()</a> function returns the actual number of bytes read.
<p>
The <a class="el" href="classPChannel.html#z55_2">GetErrorCode()</a> function should be consulted after <a class="el" href="classPSocket.html#a0">Read()</a> returns FALSE to determine what caused the failure.
<p>
<dl compact><dt><b>Returns: </b></dt><dd>
 TRUE indicates that at least one character was read from the channel. FALSE means no bytes were read due to timeout or some other I/O error. </dl>
