C equivalent of autoflush (flush stdout after each write)?

Question

In Perl, I can type: ``` $|++; ``` and anything printed to STDOUT will be automatically fflush()ed. Is there an equivalent in C? In other words, is there some way I can tell stdio to automatically fflush stdout after every printf(), the way it automatically flushes stderr?

Accepted Answer

Try `setvbuf(stdout, NULL, _IONBF, 0)`. It changes `stdout` to unbuffered (`_IONBF`) mode.
