<p>
Select a socket with available data. This function will block until the timeout or data is available to be read or written to the specified sockets.
<p>
The read#, write# and except# lists are modified by the call so that only the sockets that have data available are present. If the call timed out then all of these lists will be empty.
<p>
If no timeout is specified then the call will block until a socket has data available.
<p>
<dl compact><dt><b>Returns: </b></dt><dd>
 TRUE if the select was successful or timed out, FALSE if an error occurred. If a timeout occurred then the lists returned will be empty.</dl>For the versions taking sockets directly instead of lists the integer returned is &gt;0 for an error being a value from the <a class="el" href="classPChannel.html#z55_0">PChannel::Errors</a> enum, 0 for a timeout, -1 for the first socket having read data, -2 for the second socket and -3 for both. <dl compact><dt><b>Parameters: </b></dt><dd>
