NSLog a double* variable?

Question

- (void) _getPoints: (double*)arg1
{
  NSLog(@"%f", arg1);
}

This works for double and float, but not double*. Any help is appreciated.

Answer 1

Assuming arg1 is pointing to some sort of double you want:

- (void) _getPoints: (double*)arg1
{
  NSLog(@"%f", *arg1);
}

You might want to refer to pointer tutorial to understand what is going on, such as this.
