Process A read stdout of subprocess using pipe redirect.
but subprocess dont invoke fflush after printf, so processs A cant read anything from pipe before subprocess run to end.
ps: I have souce code of subprecess, but its very hard to modify them.
So whether Process A can force subprocess refresh stdout buffer to read something before subprocess run to end? (the same effective as fflush)
