sending to an unconnected port [message #1782554]

Hi,

sending a message to a port that has no connectors should not result in code that seg faults, right?

Rather, the 'send' statement should return '0'. E.g.,

if ( pingPort.ping().send() ) {
log.log( "ping sent!");
} else {
log.log( "Error sending Ping!");
}

should print the error message.

Did I get this right?

Thanks!

Juergen

Correct. Sending a message to an unconnected port should not result in a segfault.

See the attached model as an example. Running the model results in this trace:

[-bash|vagrant@precise32:src] > ./TopMain 
Controller "DefaultController" running.
[Capsule1](State1)
- error: message not sent

So no segfault.

If you are seeing a segfault, there might be a different problem with your model. Try doing a "make clean" and then remake to rule out any linkage issues.
