You should really be checking what open returns, opening /dev/stdout
for reading is a bit weird not sure if that would work, and most
likely it's already open... Just use fileno(...):-

#include <unistd.h>
#include <stdio.h>

int main(void) {
  write(fileno(stdout), "Hello world!\n", 13);
  return 0;
}
