I'm trying put gawk inet connection to the local smtp port and would like it
to detect error conditions, but don't know how.
Here's the code ...
awk '
BEGIN {
GAWK_SOCK_RETRIES = 2; # this doesn't seem to do anything
serv = "/inet/tcp/0/localhost/25";
print "help" |& serv;
}
'
It works when sendmail is running. But when I stop sendmail, running the
above code just hangs without reporting any error. Running "telnet localhost
25" returns error right away.
Thanks,
Jeff
