Well why not create your own function?

std::string HexToStr(const int value, int width)
{
	std::string hexStr;
	std::stringstream num;
	num.width(width);
	num.fill('0');
	num << std::fixed << std::hex << value;
	hexStr = "0x" + num.str();
	return hexStr;
}

Usage: std::cout << HexToStr(0x0004, 4);
