Outputing files to the PC with ofstream in Autonomous

[Coupon4504]

In by Test function, I have the following code to output gyro values. I was wanting to record values every 10 miliseconds and save them to a file to plot, where I would experiment with different PID values.

void Test()
{
	static const double Kp = 0.03;
	gyro->Reset();
	std::ofstream file("gyro.txt");
	while(true)
	{
		double angle = gyro->GetAngle();
		static int revolutions = 0;
		if(file.is_open())
		{
			file << revolutions << '\t';
			file << -angle * Kp << '\n';
			SmartDashboard::PutString("Error: ", " ");
		}else
		{
			SmartDashboard::PutString("Error: ", "Cannot load file");
		}
		Wait(0.01);
		revolutions++;
	}
	file.close();
}

The problem is file.is_open() always returns false. Is there something else I need to do to get files to be created?
