PWN IO Buffering
From b01lers
We need to set our IO to non-buffered mode if we want it to work over xinetd and networking because…well, because reasons.
Probably you want to use a template like this:
<syntaxhighlight lang="c">#include <stdio.h>
int main() {
setvbuf(stdout, NULL, 2, 0); setvbuf(stderr, NULL, 2, 0);
/* challenge code here */
}</syntaxhighlight>
