it is in the base code and I suppose shuld work even for Core and Electron. no way to test.

going to extend example and description ... which will be much way longer that the change itself :-)


```cpp

// SYNTAX

if (udp.isValid()) {
// seek available data ...
} else {
// udp socket not valid
}

```

{{/if}}
