Francesco,
I don't think your question has to do with RTL.... but I HAVE written a
program which collects data via an RT process and passes off the data
to a non-RT process, which proceeds to redistribute the data to client
processes via sockets. It seems to work OK....
I can send you my source code although I am hardly an expert on this subject.
Email me off the rtl list with questions on this topic. But as long as I am typing
this, I'll take a shot at it....
Things look OK..... except you may need to call htons(port_number) before
you bind.... I forget the specifics, but their is a byte order reversal that exists
between client & server..... this may only be true if your host is one endian
type and your client another (as is my case)... but if this is true then your
clients may be trying to connect to port number 25115 (0x621B) instead of
7010 (0x1B62).

Subject: [rtl] Trouble on STREAM Socket Connections
Setting Up aSocket Stream Client Server Connection un RTLinux I found
the following troubles:
The Server does not seem to send SIGIO signal to Client on sending
the message (or is the client that does not linsten to the signals..)
What I've done is:
On server:
mysock = socket(AF_INET, SOCK_STREAM, 0)
bind.....
listen....
ClientSock=(accept(......))
send(ClientSock, buf,100);
On Client:
mysock = socket(AF_INET, SOCK_STREAM,0);
connect(......)
fcntl(mysock, F_SETOWN, getpid());
signal(SIGIO, HandSigio);
while(1)
sleep(1);
then the event handler:
void HandSigio(int sig)
{
read(mysock, buf, dim);
...
}
The trouble I never have the reception of the socket packet...
what's wrong?
