arduino serial print structure

struct Gyro_data_structure
{
    char command_name[6];
    int gyro_X;
    int gyro_Y;
    int gyro_Z;
};

struct Gyro_data_structure Gyro_data = {"Hello", 48, 49 , 50};

int size_gyro = sizeof(struct Gyro_data_structure);

void setup() 
{
  Serial.begin(9600); // opens serial port, sets data rate to 9600 bps
}

void loop()
{
  send(&Gyro_data);
  Serial.println();
  delay(1000);
}

void send (const Gyro_data_structure* table)
{
  Serial.write((const char*)table, size_gyro);  // 2 bytes.
}

bool receive(Gyro_data_structure* table)
{
  return (Serial.readBytes((char*)table, sizeof(Gyro_data_structure)) == sizeof(Gyro_data_structure));
}

Serial.write(str)
Serial.write(buf, len)

Parameters
Serial: serial port object.
val: a value to send as a single byte.
str: a string to send as a series of bytes.
buf: an array to send as a series of bytes.
len: the number of bytes to be sent from the array.
