It would work but it seems rather pointless; the only reason you would
use those functions is if you have something else useful to do while
waiting for the query result ... and this program structure isn't
very conducive to doing other stuff while waiting. Usually you'd want
to have a main loop that can dispatch handling of various events, one
of them being checking for an available query result.
The whole thing is a bit of a stone-age technique anyway; if you were
thinking of starting a new program today you'd probably use threads in
preference to an event loop.
