D - Question on 'out' parameter

Hi, i have one question about 'out'.
I compiled the following D program,

//-------
import c.stdio;

void foo(out int bar)
{
}

int main( char[][] arg )
{
int bar = 3;
foo(bar);
printf( "%d", bar );
return 0;
}
//-------

and executing this, "3" was printed. But the online documentation (
http://www.digitalmars.com/d/function.html ) says that bar should be "0". Which
is the expected behavior?
