Hi, how do I return an integer from a subscriber callback in cpp?
Just return the integer with
// return integer; e.g return 0; // or if the integer is stored in a variable int ret = 0; // .... return ret;
That said, what is the use case for returning an integer in you subscriber callback? How do you intend to use the return value? Please note that, by convention, C(++) functions return
0 to indicate they were successful, and any non-zero to indicate failure.
Hi thanks for reply, I do not need that anymore!
