How can I associate a callback with the link status of a block in Simulink?

I have created some library blocks and I would like to issue a warning if the link to those blocks is ever broken. However, there does not appear to be a way to execute a callback based on the link status of a block.

The ability to create a callback for the link status of a block is not available in Simulink.

To work around the issue, you can evaluate the link status of all the model's blocks in a model callback, such as the Model Initialization function.
