Routines

Opening and Closing DDP Sockets

DDP delivers datagrams from socket to socket. You must open a socket before you
use DDP to send or receive a DDP datagram.

• You use the POpenSkt function to open a DDP socket and associate your socket listener with it.
• You use the PCloseSkt function to close a socket that you opened with the POpenSkt function.

To receive a DDP datagram from another socket, you must provide a socket listener to receive packets and your own routine to read the data. When you open a socket, you specify a pointer to the socket listener for that socket.
