Subject should be "how to take down a system [...] with three lines of
badly written C, provided you have root privileges already and are too
lazy to just dd if=/dev/zero of=/dev/ad0s1 count=100", which would
accomplish the job much faster.
Purely in the interest of showing off, here is my version. It is 81
bytes shorter than yours, it is valid C99 with POSIX extensions (yours
is not), and it produces 11,450 files in about 0.2% of the time yours
takes to produce 10,000.
#include <unistd.h>
#define b(i,v) for(int v=48;v<127;++v){f[i]=v;
#define a(i) b(i,v##i)
int main(void){char f[5]={'/'};a(1)a(2)a(3)truncate(f,0);}}}}
