Hi, how do I return an integer from a subscriber callback in cpp?
Hey @mpheng96,
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!
