Re: How to share the same internal port number in RPG socket programming

Hi David,

If I'm following you correctly, and you're using TCP sockets (AF_INET/SOCK_STREAM) and you just want a separate process to be handling the receives from the one that's handling the sends. Both programs are on the same socket, yes? If that's the case, let the first program establish the connection, then use the spawn() API to launch the second program. The spawn() API can make a copy of the socket and pass it to the other job.

I want to create two RPG programs, both connected to the same external IP
address and port number and both sharing the same internal port number.
Specifically I want one program to be sending out over the port and I want a
different program to receive the tcp/ip packet(s) from the remote system in
response to the sent packet.

Is this possible, if so could you simply explain what needs to be done, and
finally can you reference me to any examples?
