single threaded application, that selects between stdin and a listeningsocket.

[Klaus]

Hi,



I would like to write a non blocking single threaded application in
Linux, that:

1.) acts as a single client TCP server. (no forks)
A user should be able to connect to a port, and send a command

2.) reads data from stdin


Reading via the socket and stdin should be non blocking.
Therefore I guess, that I should use the select() (or perhaps poll())
command.

I do know how to use select() as soon as a client has connected,
but I don't know how to wait ( listen() ) and still be able to treat
input from stdin.

Any hints?


Thanks in advance and bye

This is a pseudo sceleton of a main function:

main(){

int clientconnected=0;



while(!end){
if(!clientconnected){
select_call(stdin,listensocket); // THAT'S WHERE I NEED
// HELP
if(datafromstdin){
treatstdin();
}
if(listendata_available){
sock=accept(listensocket,...);
clientconnected=1;
}
} else {
select_call(stdin_socket);
ifif(datafromstdin){
treatstdin();
}
if (datafromsocket){
treatsocketdata();
}
}
}
}

Not possible in ISO standard C. Ask in comp.unix.programmer or a Linux
newsgroup.
