RE: Timeout on connect?

[Jim Langston <jlangston@xxxxxxxxxxx>]

>From my blocking TCP/IP experience, you can't set a timeout on a read.

You may, however, be able to use select() to see if any data is waiting
before you try the read.

99% of my TCP/IP programming is in Pascal, C or C++, however, so I don't
know the RPG syntax of the Select() command.  select() is the C/C++ version.
Not sure how this translates to RPG.

Basically something like (in pseudo code):

if ( select(socket) )
        read ( data, socket );

in a cycle.  If you want to wait 10 seconds for data something like:

StartTime = Timer;
while ( Timer - StartTime < 10000 )
        if ( select(socket) )
        {
                read( data, socket );
                return data;
        }

ShowMessage( NULL, "No data to receive", "Error", MB_OK );

Some of the syntax of those C calls are way off and won't work in C, but it
should give you the idea.  I *believe* I'm using select with blocked sockets
in my c++ program (don't have code here to confirm, it's a home project).

HTH,

Folks:

Does anyone know if it's possible to set a timeout on a TCP/IP connect?

My research indicates that there is no easy way to do this ... I found
http://www.developerweb.net/sock-faq/detail.php?id=36 which talks about
setting the socket into non-blocking mode, which I really don't want to do
at this point (it would change my applications structure more than I'm
willing to deal with now).

Thanks!
