shutdown alll nodes

Hi,

I want to shutdown all nodes from within a ros node. ros::shutdown() kills the current node but does not kill the other nodes.

I know that all nodes can be killed using the terminal and through the launch file. But I test if a certain condition is met and only in such a circumstance I want all the nodes to shutdown.

Thanks!

If all your nodes are launched by a single launch file, you could make your checking node required and let it stop itself to take down the whole launch file. If you have several launch files, have a required node in each launch and connect the killer nodes with bonds.

Hi, the rosnode.kill_nodes and the API is for the python variant. I am not able to find the C++ equivalent.

@NEngelhard's method is the next way that I was going to suggest.
