Bridge.get for values with variable length

Projects Libraries
1

Dear Friends,

I'm using the bridge library to share data between the arduino and the Linux processor, in the following way:

char c[1];
Bridge.get("item", c, 1);

That works very well, but now I need to share an item, wich can be variable in length (an integer, for example 234, 5678, 1, 44444, etc).

How can I retrieve the result if I don't know the length of the value?

Thanks in advance

Either use a value that you know is large enough (16 is plenty for any int value) or use two calls - one to get the length and another to get the value.
