synchronisation between two executable

i have two executable to run simultaneously(say a.out and b.out) i
cant make subroutine just for now. the plan is something like:
i. b.out runs first and generates some output.
ii. this output works as the input of a.out, and again creates input
for b.out.
and this goes on in a loop.

i have a idea of how much time b.out can take, and until now i make
a.out to sleep until b.out creats the file, which is worst way of
doing it.
can anybody suggest me a better idea to make it?
.
