Hello,  
I am trying to connect our frontend to Julia via the provided uv streams (JL\_STOUT,…). The goal is to receive all outputs and show them in our own terminal. However when calling uv\_is\_readable it returns 0. Also uv\_read\_start returns 0 when connecting to the streams. But when Julia is generating output the callbacks are called and I also receive the right buffers. But it feels wrong to ignore the return values. Do I might miss something?

Thanks,  
Kane
