Enabling Callback Functions After They Error

If an error occurs while a callback function is executing, then:

• The callback function is automatically disabled.
• A warning is displayed at the command line, indicating that the callback function is disabled.

If you want to enable the same callback function, you can set the callback property to the same value or you can disconnect the object with the fclose function. If you want to use a different callback function, the callback will be enabled when you configure the callback property to the new value.
