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?
Try
setvbuf(stdout, NULL, _IONBF, 0). It changesstdoutto unbuffered (_IONBF) mode.
