Layered Service Provider for Windows(LSP)

Hi,

I am creating a Layered Service Provider for windows to check outgoing packets.

When I am in the WSPSend function I look through the data and if it meets a certain condition,
I am interested in connecting the socket up to my listening server on Windows, so that instead of the packet
being sent out to the website, it goes to my server.

Do you by chance know how to reconnect the socket without causing errors in the programs that
made the connection, to the listening server I created. <-- want to reconnect the socket within the WSPSend function of my lsp dll, so the packet can be sent to my server instead.

 I tried connect, but throws a -1 error.

Thanks,
Matt

"If no error occurs and the send operation has completed immediately, WSPSend returns zero. Note that in this case the completion routine, if specified, will have already been queued. Otherwise, a value of SOCKET_ERROR is returned, and a specific error code is available in lpErrno. The error code WSA_IO_PENDING indicates that the overlapped operation has been successfully initiated and that completion will be indicated at a later time. Any other error code indicates that no overlapped operation was initiated and no completion indication will occur."

so, which error code's value is -1, could you please clarify? thanks, bbao
