you are printing the raw data blob not the lines and you requested line
buffering in the flags - see the difference? you just never look at the parsed
lines in the event handler cb. if you don't want that then you can use the
ev->data blob and not use that flag (its a binary blob so ensure u nul terminate
it if you want it as a string and want to print it out... - then it contains
whatever data it managed to get that time - maybe cut off mid-line).
adding the event handler after running the exe happens to work because no input
is processed yet until the loop runs. its generally not a good idea though to
do this and always set up handlers first before anything that could trigger
those events.
