child processes

child processes

[Gerald Waugh]

I am not doing a good job of explaining my requirements, but I am looking for
ideas...
 I have an assignment to do an applicaiton that must communicate on
three different TCP ports...
I was wondering if I could run a daemon that would create three child
processes, one for each of the tcp ports?
Then have the daemon run any time there was communications activity on any of
the ports
The daemon must translate the data coming in any one of the ports to a protocol
acceptable to the port the data is to be sent to.
Any ideas?.

man select

select allows for "synchronous I/O multiplexing"

"The  functions  select  and  pselect wait for a number of file
descriptors to change status." - man page

You can use these descriptors to be socket fd's
