You can specify TCP or UDP timeouts for connection, accepting, reading, and
writing with setioattr (pipe-name, timeout-name, timeout-value). timeout-name
should be one of "ctimeout", "atimeout", "rtimeout", and "wtimeout".
timeout-value is a number specifying the actual timeout in milliseconds.
A negative value indicates no timeout.
You can call getioattr (pipe-name, timeout-name) to get the current
timeout-value set.
See the example below.
@code
BEGIN {
setioattr ("tcp://127.0.0.1:9999", "ctimeout", 3000);
setioattr ("tcp://127.0.0.1:9999", "rtimeout", 5000);
print "hello world" || "tcp://127.0.0.1:9999";
"tcp://127.0.0.1:9999" || getline x;
print x;
