<div class="markdown_content"><p>Does anyone have experience using the Sockets library with TCP/IP? I am trying to develop a TCP/IP application and have gone through the Create-Bind-Listen sequence on the server without a problem. When I try to accept however, I am getting a negative number for the new socket number, typically -2134 (FFFFF7AA) but sometimes -2548 (FFFFF60C). Is a negative socket number legal? I can't seem to get the receive command I have after the accept command to work with this negative socket number so I think it's not legal. Is this an error code? I can't find a list of error codes for the socket commands in any documentation I have.</p> <p>Any help would be appreciated.</p></div>
