000000000000000 when writing to a file/stdout

[Martin Bähr]

hi,

i am trying to run pike as a daemon with stdout redirected:

void main(int argc, array argv)
{
  if (sizeof(argv)<2 || argv[1] != "daemon")
  {
     int i = 100;
     while(i--)
     {
         write(i+"\n");
         sleep(0.1);
     }
  }
  else
  {
      Stdio.File newout = Stdio.File("foo", "wc");
      Process.spawn_pike(({ "daemon.pike" }), ([ "stdout":newout ]));
  }
}

this works, but when the program is done, the file is appended with 381018 bytes worth of:
000000000000000000000000000000000000000000000000000000000000000000000000000 ^H0000000000000000000000

it is always the same amount, and i can't tell what causes this...

greetings, martin.

there must be something system dependent going on though, because now
the problem is gone, without a change of the code.

i have seen this symptom before when dealing with stdio.
i wonder what is going on here...
